The story follows Luke, a survivor from the first film, who tries to convince others that beautiful female aliens are once again on campus, seducing students to breed and propagate their species.

Decoys 2 doesn't try to be high-brow cinema. It thrives on "B-movie" energy, blending practical creature effects with the "slasher" formula. It explores the classic sci-fi fear of "the enemy among us," disguised as the very thing the protagonists desire most.

: A group of beautiful female aliens (decoys) has infiltrated the campus to mate and save their species from extinction.
