Magnum and Higgins go undercover as a couple on a romantic wilderness tour to tail a man suspected of cheating on his wife. However, their original assignment takes a back seat when an older man on the tour, who recently remarried, is found dead in a body of water down a steep drop. Magnum determines the man was dead before the fall, making everyone in the tour group a suspect. Elsewhere, TC reconnects with his old flame Teresa, whom he learns moved on and married another man while TC was missing in action.
