A one-time Interpol undercover agent, Johnny Walker, is asked by a friend, Baumstark to come rescue him from marauding rebels that have taken him and his granddaughter hostage. The evil African rebel leader has learned the archeological dig Baumstark was working on just might yield a biblical relic, a tiara called the Devil's Crown. Legend has it that the wearer will gain supernatural powers endowed by the devil himself. Complications arise when the agent finds the rebel is his old nemesis and Baumstark's sixteen-year-old granddaughter Heather is enamored with him. In time the attraction is mutual, but for ethical reasons the two postpone their relationship. The cooling off five-year period involves Walker leaving Africa to join another of his friends who is on a dangerous treasure hunt in the Atolls. When Walker returns to resume his romantic quest, Walker and Heather finally wed. But just as the honeymoon is consummated, an old flame shows up and Walker is literally caught with his pants down.
