Visiting England for the first time, American Brad Hunter and his wife Suzy are looking forward to seeing the sights. As soon as he arrives, however, Hunter begins to lapse into episodes of bizarre behaviour; first he repeatedly refers to his wife as "Theresa" , and then flies into a rage and throws a business colleague out for no reason. Seized by strange sensations of familiarity about his new surroundings, Hunter's personality begins to disintegrate as he imagines himself to be an Englishman named Charles Merrow. To aid in solving the mystery, an eccentric private detective named Matthew Earp is called in but Hunter has already attracted the attention of other parties who's intentions are far from friendly.
