The couple from hell turn the tables on Gus (Leary), a hard-nosed fugitive who takes Caroline (Davis) and her husband Lloyd (Spacey) hostage. Gus then finds himself trapped in the traditional Christmas ordeal of a family suffering from industrial-strength dysfunction. He plots his getaway while masquerading as the couple's marriage counselor, hence the film's title. This sometimes brutal, frequently hysterical satire of male-female relationships, family ties, and compulsory holiday rituals uses consistently sharp dialogue and superb acting to tell an absurd but convincing tale.
