Lennox takes on a gang of race-fixing gamesters.
Horse racing has returned to Los Angeles, and the bright lights of Hollywood are flocking to the track. When a General-Consolidated studio executive buys an interest in a prime nag, studio troubleshooter Bill Lennox makes a point of keeping an eye on the horse. He smells a rat during the first race; the jockey rides the horse softly, finishing near the bottom of the pack. That night, Lennox gives the man a simple warning: Either ride the studio horses honest, or don't ride them at all.
The jockey is terrified — not of Lennox, but of the gamblers who paid him to throw the race. He tries to stand up to them, but it's no more than a few hours before his newfound nerve gets him killed. Lennox has to clean up the track before more innocents die — in a race against corruption that is sure to come down to a photo finish.
