Batgirl and Robin are captured separately by the Sportsmaster and the Huntress and forced to compete in ancient Roman-style games against one another so that the survivor may retrieve a giant ruby for them--or face their partner's death. The young heroes manage to keep the score even thanks to a silent agreement and they are both forced to go down a trap-hole to retrieve the ruby. Working together, Batgirl and Robin manage to retrieve the gem and defeat the clumsy criminals. Their feat is reported by the Gotham Gazette and when Alfred and Bruce read the latest news, they both feel proud and satisfied with the young heroes.
