The setting is Hollywood in 1942, and someone is out to kill John Wayne, in this 11th adventure featuring private gumshoe Toby Peters. A man named Lewis Vance lures Toby to his hotel room, ostensibly to hire him for a case. But Toby, after awakening from a stupor induced by a drugged Pepsi, finds himself in the room with Vance's corpse on the bed and John Wayne pointing a .38 at his chest. Wayne has also been lured there by a cryptic phone call and is suspicious of the P.I., but when he learns that Toby is a chum from his old neighborhood, the actor hires him to find the real culprit. The case gets more tangled when Toby discovers a link between Vance's alleged killer, a shady desk clerk named Teddy Spaghetti, and the theft of a $10,000 donation (made by Charlie Chaplin) to a charity promoting Soviet-American relations; he soon find himself in Chaplin's hire to recover the stolen money.
