Yo-yo

Burt meets Jack Costello after many years. Burt is a boxer and he is fleeing after a fixed match that he should have lost but instead he won. Then he vanishes. Costello finds in his office Burt's son, 'Jo-Jo' Ritchie, who had came because his father had ordered him to go to him. Then Jo-Jo cames back to Groggy where he lives and when the two of them are dining, two men arrive and kill Groggy. Jo-Jo runs away and Extralarge sets on finding him and his father.
