The Big Parade
In the United States in 1917, James "Jim" Apperson's (John Gilbert) idleness (in contrast to his hardworking brother) incurs the great displeasure of his wealthy businessman father. Then America enters World War I. Jim informs his worried mother that he has no intention of enlisting, and his father threatens to kick him out of the house if he does not join. However, when he runs into his patriotic friends at a send-off parade, he is persuaded to enlist, making his father very proud.
During training, Jim makes friendships with construction worker Slim and bartender Bull. Their unit ships out to France, where they are billeted at a farm in the village of Champillon in the Marne.
All three men are attracted to Melisande (Renée Adorée), whose mother owns the farm. She repulses all their advances, but gradually warms to Jim. They fall in love, despite not being able to speak each other's language. One day, however, Jim receives a letter and a photograph from Justyn (Claire Adams), which reveals that they are engaged. When Melisande sees the picture, she realizes the situation and runs off in tears. Before Jim can decide what to do, his unit is ordered to the front. Melisande hears the commotion and races back, just in time for the lovers to embrace and kiss.
The Americans march towards the front and are strafed by an enemy fighter before it is shot down. The unit is sent to the attack immediately, advancing against snipers and machine guns in the woods, then more machine guns, artillery, and poison gas in the open. They settle down in a makeshift line. Jim shelters in a shellhole with Slim (Karl Dane) and Bull (Tom O'Brien).
That night, orders come down for one man to go out and eliminate a troublesome mortar crew; Slim wins a spitting contest for the opportunity. He succeeds, but is spotted and wounded on the way back. After listening to Slim's pleas for help, Jim cannot stand it any longer and goes to his rescue against orders. Bull follows, but is shot and killed. By the time Jim reaches Slim, he is already dead. Jim is then shot in the leg. When a German comes to finish him off, Jim shoots and wounds him. The German starts crawling back to his line. Jim catches up to him in another shellhole, but, face to face, cannot bring himself to finish him off with his bayonet. Instead, he gives his erstwhile enemy a cigarette. Soon after, the German dies. Fortunately for Jim, he is not stuck in no man's land for long; the Americans attack, and he is taken away to a hospital.
From another patient, he learns that Champillon has changed hands four times. Worried about Melisande, Jim sneaks out of the hospital and hitches a ride. When he gets to the farmhouse, he finds it damaged and empty. Melisande and her mother have joined a stream of refugees. Jim collapses and is carried off in an ambulance by retreating soldiers.
After the war ends, Jim goes home to America. Before he arrives, his mother overhears Justyn and Jim's brother Harry (Robert Ober) discussing what to do; in Jim's absence, they have fallen in love. When Jim appears, it is revealed that he has had his leg amputated. Later, Jim tells his mother about Melisande; she tells him to go back and find her. When he returns to the farm, Melisande rushes into his arms.
