The “bad apple” of the Johnstone family, Sammy begins the play as an object of envy for his younger brother, Mickey. Dropped on his head by a young Donna Marie when he was a baby, Sammy quickly becomes a juvenile delinquent, even trying to rob a bus as a teenager. Eventually, the adult Sammy turns to a life of crime, and persuades the unemployed Mickey to help him. This attempted robbery, however, ends with a murder, and Sammy presumably winds up in jail, as does Mickey.
