A couple of small favors land Flash Casey in a dangerous mess. Flash Casey should know better than to take a roll of film from a desperate man. Stopping for a drink on his way home from work, a fellow news photographer gives him a canister to safeguard. The next morning, Casey wakes up with gunmen in his bedroom, looking for the film that could implicate one of their associates in a killing. To save his friend's life, Casey hands over the negatives, expecting that to be the end of it. He's wrong. A stockbroker named Donald Farrington spent the night at the same bar, getting into a different kind of trouble -- the sort that ends with him being photographed in a hotel room with a woman who isn't his wife. Casey agrees to help him navigate the blackmail, a friendly offer he'll regret very soon.
