An ex-football player and a crooked insurance man cook up a blackmail scheme. Professional football player John Harlan is driving back from a lakeside cabin when a drunk driver named Cannon knocks him off the road. When he comes to, Harlan's leg is shattered and Cannon is dead. His career over, Harlan goes on a bender, and a few days after his hangover clears, he dives headfirst into a life of immorality. An insurance investigator named Purvis is checking into Cannon's death, hoping to avoid laying out $100,000 to his widow. He suspects Cannon may have survived the accident, only to be murdered while Harlan was unconscious -- and the more he talks about it, the more Harlan believes it. They devisea plan to blackmail dear Mrs. Cannon, but if Harlan was a pro on the field, he's an amateur in the underworld. Next to what the lovely widow is going to do to him, football is a cakewalk.
