Soul Breaks Blue Bridge

A military vehicle pulled up on Waterloo Bridge and British Colonel Roy Cronin stepped out of it. Cronin stepped out of the car. He took out ivory carved good luck charm from his pocket and gazed at it alone from the railing, a love affair of twenty years ago was in sight ......

London, 1917, during the First World War. The air raid sirens sounded and people in the streets ran in panic to the air raid shelters. A group of young girls darted across Waterloo Bridge. Suddenly, one of them had her carrier bag knocked off and spilled her things all over the place. She stopped to pick it up and was about to be hit by a speeding carriage. A young captain officer, Roy Cronin, was also at Waterloo. Cronin, a young captain officer, was also running on Waterloo Bridge, and he pulled the girl out of the way in time to avoid the carriage. Roy picked up the things scattered on the ground for the girl, among which was the ivory good luck charm, which was dear to her. When the girl could not find her companion, Roy took her hand and ran into the crowded underground railway. In the noisy crowd, Roy talked to the girl. The girl's name was Mara, a ballerina. Mara took a liking to the suave young officer and talked to him about her love of dancing. Roy tells the girl that he is on vacation in England, that his leave has expired, and that he will leave for the French front tomorrow. When the alarm is lifted, Roy calls a car for Mara and rushes to the theater to perform, while he goes to a party that his boss cannot refuse. Before leaving, Mara gives Roy her beloved good luck charm: "May it bring you luck." Roy had fallen deeply in love with this dignified, beautiful, and innocent girl, and looked at Mara's departure with a sense of loss.

Roy finally didn't go to his boss's party, he went to see Mara's performance of "Swan Lake". After the show, he handed a note backstage, inviting Mara to dinner. The note was confiscated by the theater manager Madame Delva, who sternly reprimanded Mara. Mara goes behind the manager's back to the Candlelight Club. In the lobby, Roy pours out his love to Mara, and the two dance to the waltz of "Safe Journey". The candles are extinguished one by one as each part of the song finishes, and the hall is immersed in darkness. Roy and Mara looked at each other with affection and embraced for a long kiss.

The next morning, with light rain falling outside, Mara looked out of her dormitory window, thinking of Roy on the English Channel. Suddenly, she is surprised to find Roy in the rain. It turns out that Roy's troops have been delayed by two days because of mines at sea. Roy proposes to Mara and Mara happily agrees. The marriage of an officer of the Lentscher Legion, who comes from a noble family, requires the approval of the Duke. Roy buys a wedding ring for Mara and rushes to the Duke's residence. Although Mara was a commoner, the cheerful duke agreed to Roy's application. Roy arrived at the church with Marla in a frenzy, having completed the other necessary formalities. However, they were late, and according to the law, the wedding could not take place after three o'clock in the afternoon. Roy agreed with the priest to come back tomorrow at eleven o'clock sharp.

That evening, Roy was called back to the barracks, and Marla, who was about to become a bride, was immersed in sudden happiness. Just as she was about to go to the theater with her girlfriends, she received a call from Roy: the troops were to leave early, in twenty minutes. Against all odds, Mara rushes to Waterloo station, where the train has already started.

Mara delays the evening's performance because she insists on going to the station to see Roy off. Madame Descartes is furious; she cannot tolerate a world outside of ballet for the cast, and she wants to fire Mara. Her best friend Katie suffers the same fate for speaking up for her. The two lose their jobs and move together to a cheap apartment, where they are dependent on each other.

Careful Roy writes to his mother to meet with Marla so she can take care of her. But while waiting for her mother in the restaurant, Marla overhears Roy's name in the newspaper and sees it on the list of the fallen. At this point, Roy's mother comes to her, and although the noble lady is very kind, Marla is in a state of emotional turmoil, rude and uninformed. ...... Desperate, Marla cannot bear the shock and falls ill. Katie is forced to work as a prostitute to pay for her living expenses and Mara's medical bills. After recovering from her illness, Marla discovers the breakage and is extremely grateful for Katie's friendship. With Roy dead, nothing in the world matters to her anymore, and she can't leave Katie alone with the burden of two people. After healing, Mara is also reduced to a street call girl to make ends meet.

Waterloo Station. Marla, a prostitute, is heavily made up, flashing her eyes and beckoning the officers and men who walk by. Suddenly, she froze: a familiar figure walking towards him, it was Roy, he was not dead, he was back! Seeing Mara, Roy was so excited that he couldn't hold himself back, and Mara had mixed feelings and howled.

In a restaurant, Roy excitedly recounted to Mara how he had come back from the dead: he had been wounded and lost his papers, had been a German prisoner of war, had almost died but had finally escaped. Mara listened quietly ...... When Roy asked about her life, Mara was speechless, only saying over and over again, "If only I had known you were alive." Roy, who had experienced life and death, did not want to take another step away from Mara. He immediately called his mother and told her he was taking Mara home to get married. Marla painfully rebuffed Roy. After being convinced that Mara had not fallen in love with him, Roy took her home without a word.

On the way, Mara snuggles up to Roy, watching the idyllic scenery of Scotland and listening to Roy's description of her home and plans, a good wish rises in her heart. Roy's trust and affection gave her a glimmer of hope, and she knew that her heart was still jade and ice, and she wanted to wait for the opportunity to explain everything and start her life anew.

The Cronin house in Scotland. Mrs. Cronin greeted them with joy. In the evening, the ballroom was brilliantly lit, and Mara's beautiful dancing was most striking. But the noblewomen in the seats are whispering about the fact that the Cronin family is marrying a dancer. The Duke comes to the ball and lovingly invites Mara to dance. During the conversation, he praises Mara's kindness and loyalty and informs her that the Cronin family has always attached importance to family rank and that Mara is an exception. Mara, who had just calmed down, was again in a state of apprehension.

Late at night, Mara wanders restlessly in her bedroom. Mrs. Cronin knocks on the door and asks Mara to forgive the misunderstanding of the meeting in London and expresses her satisfaction with her son's marriage, she praises Mara as a perfect person. Madame leaves, and Mara realizes that her past experiences will not be understood by the people of high society, and she is unwilling to maintain the illusion. Mara runs to Madame's bedroom and tearfully explains the truth, saying that she wants to leave Roy forever. Madame did not detain her and promised not to tell Roy the truth. When she comes out of Madame's house, she meets Roy, who is too happy to sleep. Roy does not notice Mara's perversity and lovingly hands the amulet back to Mara for safekeeping. Mara sadly says goodbye to Roy.

She leaves a farewell letter thanking him for his love and leaves the Cronin house. Roy chased her to London and found Kitty, who explained everything to him. Roy said sadly, "I'm going to look for her forever." They searched every possible place, but Marla was nowhere to be found.

By this time, Marla was on Waterloo Bridge. A convoy of military trucks rumbled by, and Marla stepped fearlessly toward a speeding military vehicle, her pale face beautiful and holy in the headlights. Amidst the shrieks of the crowd and the brakes of the trucks, Mara's life ended, her handbag and an ivory good luck charm scattered on the ground.
