Trancers is a 1984 American science fiction action film directed by Charles Band and starring Tim Thomerson, Helen Hunt, and Art LaFleur. It is the first film in the Trancers series. Thomerson plays Jack Deth, a Philip Marlowe-esque police detective from the 23rd century who travels to the 1980s to bring his old nemesis to justice. The film portrays a unique method of time travel: people can travel back in time by injecting themselves with a drug that allows them to take over the body of an ancestor.
