Adapted from his own TV play by Reginald Rose, Dino stars Sal Mineo (who also appeared in the TV version) in the title role. Sent to reform school for his complicity in a gang killing, Dino is released in the custody of kindly settlement worker Sheridan (Brian Keith). Despite the efforts by Sheridan and parole officer Mandel (Frank Faylen) to set the boy on the right path, sullen Dino intends to rejoin his old gang at the first opportunity. Only when he realizes that his younger brother Tony (Pat DeSimone) is in danger of becoming an irredeemable juvenile delinquent does Dino gets wise to himself. It also helps when he falls in love with Shirley (Susan Kohner), a "plain-Jane" girl he meets at Sheridan's settlement house. Rarely seen today, Dino is one of the better "j.d." films of its era.
