Feature-length documentary covering the making of the 1982 film XTRO.

"Superfan" Dennis Atherton discusses the film's tropes, aspects of the family drama that get ignored amidst the alien mayhem, and obsessively points out various details in the story and art direction that foreshadow other developments that suggest a degree of stylistic deliberation that cannot be explained away by Robert Shaye throwing in demands, while Bromley-Davenport tends to downplay these touches as intentional.

An underground government facility is locked down by its A.I.-controlled computer when an alien entity travels through a dimensional portal and threatens the lives of everybody inside.
