A man known only as "Catch" wanders the streets of Chicago in a trance-like state, doing good deeds for strangers and neighbors. One day he sees Sharon at a diner and watches her from across the street, and she notices him watching her. Just then a car pulls up and blasts the diner with machine gun fire, and Sharon and her partner chase after the criminals. Sharon catches up with one criminal and in the ensuing struggle, he gets her gun and shoots her twice in the chest. Seeing that she is protected by her bulletproof vest, he prepares to shoot her in the head, but Catch jumps the man and knocks the gun away, saving her life. That night, Sharon and Catch meet at a tavern and have a drink. A grateful Sharon tries to learn more about Catch, but he does not talk about himself. Sharon invites him to her apartment, and after some awkward moments between the two, they share a kiss. Catch abruptly stops and leaves the apartment, leaving Sharon confused.
