Two mob money couriers, Frankie and Tony, have their latest package of $1 million stolen by two con women, Dana and Marcia, in which the men must find the women to recover the money before they become marked men.

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.
