Jim Slocum, a taxi driver, is struck by a series of calamities. His baby is taken seriously ill, he is fired from his job when his boss wrongly believes that he showed up for work drunk, and the specialist he has been referred to who can cure his sick child refuses to see him because a rich patient demands that he sees his "sick" son, who it turns out just has an upset stomach. However, because Jim's child hasn't been seen by a doctor, his condition worsens and he dies. Jim's wife is consumed by grief, and Jim, enraged that the doctor turned him down in favor of a rich patient that resulted in his son's death, determines to take his vengeance on both the doctor and the wealthy father.
