Kathy, a young child, has befriended the elderly miser who lives on an upper floor of the building where she lives. Today, while playing outside, she also makes friends with Jules, a homeless petty thief. Later, when she is in the miser's apartment, two violent criminals break in. They tie a rope around Kathy and dangle her out of a window, threatening to let her fall to the ground if the miser does not give them the combination to his safe. Outside, Jules sees her in danger, but to help her he must risk dealing with the police.
