The Double is a sci-fi thriller about a scientist who studies astral projection, and, through a near-death experience, comes to experience something unnatural. Steven Edwards (Eric Roberts) is an established author and expert in particular phenomena that are a combination of Eastern meditation practices and occult rituals. His particular interest is in out-of-body experiences, the kind in which an astral body leaves the physical body and exists outside of it as a double. His wife (Shannyn Sossamon) is both curious and bothered by Steven's field. One day, a plane ride begins to go wrong. As passengers begin to panic and reach for oxygen masks, Steven reaches for a set of headphones, a CD player, and a recording of the messages that he gives to people. A course of professional study turns into panic in the moment of crisis, and Steven discovers dark and unexpected things about himself and about his power over the world.
