Rusty Connors is a con man that has just been released from prison. He looks up the wife of his dead former cellmate, a robber and murderer, named Miles Krause. Before he was imprisoned, Krause stole a significant amount of money and killed his partner. The money and the body, however, never turned up. Connors talks to Krause's wife Helen and hopes that she knows where the money is. She, however, does not have a clue. Eventually, however, they are able to figure out that the money is stored in an abandoned boathouse that is now infested with rats. In the boathouse, they find the money and the dead and half-eaten body of Krause's partner. When Connors sees the money he is overcome with greed and tries to murder Helen. She manages to knock him out. When Connors awakens, he finds himself bound and gagged and being taunted by Helen. She gets up to leave with the money, but is tripped by Connors and is impaled on a hook. As she dies, the scent of her blood attracts the rats.
