Kim Hunter guest stars as Crazy Annie, a skid row derelict. Undercover detective Tony Baretta (Robert Blake) invades the shadowy, squalid world of Annie and her fellow down-and-outers as he searches for an elusive killer. Before he quite knows what has happened, Baretta is kidnapped by Annie, who is convinced that the cop is her long-lost son. ~ Hal Erickson, Rovi
