The film was made by Los Angeles-based comedy group The Vacationeers and stars Rachel Boston, David Cross, America Ferrera, Jeff Grace, Erinn Hayes, Kevin M. Brennan, Blaise Miller, Julia Stiles, and Todd Berger.

After a neighbor, Hal, appears in a hazardous materials suit with news of dirty bombs exploding in major U.S. cities, including one 12 miles downtown from them, the couples begin to accept that a disaster has occurred.

Throughout the hunt, revelations of affairs between both hosts and two guests, Buck and Lexi, are made, as are rejected sexual advances by the swinger couple toward Glenn who rebuffs them.

Her now-former fiancé is a comic book trader and bases his survival strategy on what he's learned from zombie films like Night of the Living Dead.

After hearing of the bombs, he becomes highly suspicious of outsiders (including the new guy) and suggests others watch for bite marks or odd behavior, and they find weapons (like crowbars and chainsaws).

While he seems more concerned by the woman's vague and rushed description of the situation outside, her decision to leave them is also partly punishment for always being late and for a past grievance between the two women over a man at a New Year's party.
