The film centers on a group of plane crash survivors who has to survive the attacks of a giant alien spider.

The film stars Alex Reid, Chris Potter, José Sancho, Neus Asensi and Ravil Isyanov.

It was the second film under the Fantastic Factory Label, created by Brian Yuzna and Julio Fernandez in Spain.
