Several years into his exile from Hollywood, director Roman Polanski hits his stride again with this dread-filled suspense thriller. Dr. Richard Walker (Harrison Ford) and his wife, Sondra (Betty Buckley), are in Paris on business when Sondra suddenly vanishes. With no way to contact her or to communicate with the locals, Richard is paralyzed with fear. When his attempts to get the police involved fail, Richard begins the pursuit alone.
