Pop Clark is about to lose his baseball team, unless they can win the pennant so he can pay off debts. He hires ace player Larry Kelly to ensure the victory. As well as rival teams, mobsters are trying to prevent the wins, and as the pennant race nears the end, Pop`s star players begin to be killed, on and off the field. Can Larry romance Pop`s daughter, win enough games, and still have time to stop a murderer before he strikes more than three times?
