They marry and have a son, Johnny. When Tom, a thief who mentally and physically abuses Joy, is jailed for four years after attempting a big robbery, she is left on her own with their son. After briefly sharing a room with her Aunt Emm, an aging prostitute, she moves in with Dave, one of Tom's former associates.
