Shopkeeper Victor Garnier has naively invested his family's life savings in an African mine, on his banker's recommendation. When the mine is nationalized, rendering the stock worthless, he considers himself shamelessly robbed by the bank; it seems only fair to him to return the 'favor' and rob the bank, teaming up with the whole family as they were all duped.
George Fowler is drawn into a gang planning to rob a bank in St. Louis that they expect will have a $100,000 on hand on an upcoming Friday. George is drawn into the plan as the gang's driver by Gino, an old girlfriend's older brother. As the gang goes about its planning, George and Gino have to find a way to live for the next two weeks and they turn to Gino's sister, Ann, for help. George is hoping to go back to college and the money he would make would go a long way to helping him do that. Not trusting George to keep his nerve, the gang's leader John Egan moves him to the inside, but the robbery doesn't go off as planned.
