Gothic ghost story set against the gloomy backdrop of Edinburgh's spires and closes. Michael (Jamie Sives) is a young astronomer heavily involved in experiments to break down the barriers between space and time. A chance encounter with a pretty young French photographer, Caroline (Julie Gayet), develops into an obsessive love affair. Michael, though the claustrophobic nature of his work, has lost touch with reality and his mental state begins to crumble. He is soon locked in a mental struggle to discover whether he is actually a ghost or whether it is Caoline who has already passed to another dimension.
