Violent Saturday (1955)

A number of otherwise insignificant small-town stories erupt into drama when a gang of hoodlums decides to rob the local bank. A father looking for pride in his son's eyes, a timid clerk who is a peeping Tom by night, a man striving to rewin his wife's love, an Amish farmer faced with viciousness, and a proper older woman turned thief, all find themselves entangled with the bank robbers as a peaceful weekend turns violent.
