Rollie Tyler, a special effects expert, helps his detective friend solve crimes by making criminals see what they want to see. But what is real and what is illusion?

In 1863, when a legless, shipwrecked man washes up on the Acadian coast, he's taken to the home of Jean the Corsican, a burly and bitter former soldier, and his childless young wife, Julitte. The man, who is young, handsome, and well-dressed, remains mute as Julitte nurses him back to health. Jean, meanwhile, who is inexplicably estranged from Julitte and an outsider to townspeople, continues his hunt for pirate treasure, rumored to be hidden in a cave by the sea. The treasure is his ticket out of Acadia. As loneliness and Eros draw Julitte and the mysterious Jérôme together, something's got to give.
