In the year 2047, the spaceship 'Lewis and Clark' sets out to track down the missing vessel 'Event Horizon', which disappeared after its launch seven years earlier. In command is Captain Miller (Laurence Fishburne), along with 'Event Horizon' designer, Dr William Weir (Sam Neill). They are following a distress signal recently picked up from the missing craft, and when they eventually make contact the crew are besieged by nightmarish visions.
