‘We come in peace’ is not what those green men from Mars mean when they invade our planet, armed with irresistible weapons and a cruel sense of humor. This star studded cast must play victim to the alien’s fun and games in this comedy homage to science fiction films of the ’50s and ’60s.

Mary Marshall, serving a six year term for accidental manslaughter, is given a Christmas furlough from prison to visit her closest relatives, her uncle and his family in a small Midwestern town. On the train she meets Zach Morgan, a troubled army sergeant on leave for the holidays from a military hospital. Although his physical wounds have healed, he is suffering from post-traumatic stress disorder and is subject to panic attacks. The pair are attracted to one another and in the warm atmosphere of the Christmas season friendship blossoms into romance, but Mary is reluctant to tell him of her past and that she must shortly return to prison to serve the remainder of her sentence.
