The Kingpin is the biggest, the meanest, the toughest, the boss.
Set in a teenage reform school, the film centres on the new arrival of Riki Nathan, a quiet but sulky kid who just wants to do his time and get out. But in the meantime he befriends Willie Hoto, an effervescent teenage boy whose tall stories and bravado win Riki over. Willie’s small stature is in stark contrast to the bulky physique of the oppressive character, Karl. It is Karl’s ‘Kingpin’ who challenges Riki’s growing friendship with Willie, bringing about their final violent confrontation at the end.
