Carnosaurios (1993)

A brilliant geneticist, Diane Ladd, plans to expose a lethal virus to every human being on the planet. Her objective: to destroy humankind in favour of her new strain of prehistoric dinosaurs. Two people stand in the way of her diabolical plan, a cynical night watchman and a lovely idealistic environmentalist. The two must overcome their differences long enough to uncover the scientist's scheme and fight her carnivorous creations in a desperate battle against the extinction of the human race.
