Frank and Roger and their wives take off for Colorado in a recreational vehicle, looking forward to some skiing and dirt biking. While camping en route, they witness a Satanic ritual sacrifice, but the local sheriff finds no evidence to support their claims and urges them to continue on their vacation. On the way, however, they find themselves repeatedly attacked by cult members, and they take measures to defend themselves. —IMDb
Fairly ridiculous, but also incredibly entertaining 70s cult horror film. The story is fast-paced and original, and the cast gives it their all - and it ends with a very exciting car chase climax. Great fun for B-movie fans.
