The story concerns a small town sheriff who must stop a rampaging alien from killing the residents of Perry Hall, Maryland.

When Cinder's police find out that Wicker's party is in progress, Jamie bluffs that poison gas is escaping from a nearby mine and the partygoers flee in panic.

Wicker and his secretary Mary Jane, dispirited by this turn of events, stay home and begin drinking heavily.

Price and nurse Ruth hide in the basement, and devise a trap to electrocute the beast with some frayed electrical cord.

Price, thinking back to his success with the electrical trap, supports this course of action, and the sheriff drives out to the power plant with his men.

Cinder and his crew return to Wicker's house and begin setting up their trap, laying metal wire between the trees and connecting it to the coil, which will discharge when they throw the circuit breakers.

TV Guide panned the film, awarding it one out of four stars, stating, "Although the special effects (including some startling uses of gore makeup) are noteworthy, the actors aren't given much to do other than stand around and talk.

[7] Bill Gibron of DVD Talk rated it 2.5/5 stars and called it "an angry middle aged man's cry for attention".

[8] Mark L. Miller of Ain't It Cool News wrote, "All in all, Nightbeast is drive-in, beer-swilling, audience-heckling fun.

Among other things, the group discussed the film's similarity to Dohler's other work, hokey acting, and improved special effects.
