Synopsis:
Johnny Dee, star football player for Stanhope, is threatened by gamblers. If Johnny doesn't throw a game, they will hurt his girlfriend Roxie Thompson. Johnny reluctantly complies to protect Roxie.

When Johnny sits out the next game, Supergirl questions Johnny, but he refuses to admit why he isn't playing. Finally Supergirl and Roxie convince him to tell. However, Supergirl is unable to change his mind about playing.

At the next game, the crooks station sniper's around the stadium to target Roxie if Johnny plays. Supergirl rounds up the snipers, then saves Roxie. Johnny plays and wins the game for his team, while Supergirl apprehends the crooks. However, she is given a ticket for destroying property and blocking traffic to do it.
