During
World War I, working class Tom Holmes and his wealthy friend and superior officer Roger Winston are sent to capture a German soldier, but Roger loses his nerve. Tom completes their objective alone, but is then hit by shrapnel and apparently killed, leaving it to Roger to return the captive to the American lines. Roger's feeble efforts to refuse credit are dismissed as modesty, and he is rewarded with a
Distinguished Service Cross. Meanwhile, Tom is found alive by German soldiers and taken to a hospital. His life is saved, but he is left in severe pain, for which he is given
morphine pills. After the armistice, Tom is part of a prisoner exchange. Roger is shocked to see him on the boat home, but Tom indicates no desire to reveal the truth of their mission, and Roger gets Tom a job at his father's bank. However, Tom has become dependent on morphine, and, eventually, this costs him the job. He is sent to treatment, and emerges sober, but unemployed and without a family, his mother having died the day after he was committed. Tom goes to Chicago, where he finds an apartment over a diner run by the kindhearted Pa Dennis and his daughter Mary. He quickly strikes up a romance with his neighbor Ruth Loring, and gets a job as a driver for South Park Laundries. The owner, George Gibson, quickly notices Tom's ability and intelligence, and promotes him. By the end of 1926, Tom and Ruth are married and expecting a baby. Max Brinker, a German immigrant inventor who is an avowed communist, but not against getting rich, asks Tom for money to patent a machine that will greatly increase efficiency at industrial laundries. Tom invests what he can, and raises the rest from his coworkers. He negotiates a deal with Gibson to install the machine, but stipulates there can be no layoffs because of the change. All goes well, until Mr. Gibson dies suddenly of a heart attack. The new ownership further automates Max's machine and fires three-quarters of the workforce, ignoring Tom and Gibson's deal. A mob of former employees gathers outside Tom's apartment, furious he got them to contribute money to the cause of their unemployment. Tom says they have a legal case, but they do not listen, and march on the plant to destroy the machine. Tom follows to try to stop them, and is involved in the riot when police are called. Ruth is killed while trying to find Tom, and Tom is arrested as the ringleader of the mob and sentenced to five years in prison. Max, throwing off all pretensions of being a communist, sells his machine nationwide, making him and Tom rich. Tom has no interest in what he sees as blood money, but Max makes sure Tom gets his payments as part-owner of the patent, and, when Tom is released from prison in 1932, he has a bank balance of over fifty thousand dollars. He sees how Pa and Mary, who have been raising his son Bill, are struggling to feed the needy at their diner during the peak of the
Great Depression, and signs over his bank account to them. When a machine shop is destroyed by a mob, the
Red Squad kicks Tom out of Chicago, assuming he was involved. He tramps from place to place, turned away wherever he goes, alongside many other wandering men. One night, while sheltering from the rain under a
railroad trestle, Tom runs into Roger, who is in the same situation as Tom after the
stock market crash exposed his and his father's misuse of depositor funds, leading to his imprisonment and his father's suicide. Whereas Roger is cynical about the future, Tom asserts that America will be stronger than ever in a few years. They are interrupted by the local authorities and forced to move on, but Tom remarks that at least the rain has stopped. Back at Pa and Mary's diner, Tom's money is helping feed a constant stream of needy people. Mary and Bill admire a plaque honoring Tom, and Bill declares that, when he grows up, he wants to be just like his dad. ==Cast==
