Thriller starring Sandra Bullock and Julian McMahon. Linda Hanson (Bullock) is an average housewife with a loving family, but when a policeman comes knocking on her door with news that her husband, Jim (McMahon), was involved in a fatal car accident, Linda's world slowly begins to unravel. While her grief is at first overwhelming, Linda assumes that the whole thing was nothing more than a vivid dream when she wakes up the next morning to find her husband very much alive. With each passing day, however, Linda's reality shifts and her circumstances grow increasingly surreal; one day Jim is dead and the next he is right there by her side. As her investigation leaves her convinced that her husband's death wasn't a dream and that her picture-perfect life may not have been quite as flawless as she thought, Linda embarks on a mind-bending journey to prevent her grim premonition from becoming a reality.
