This coarse bedroom farce takes place at the St. Moritz ski resort over a Christmas vacation. Among the couples whose lives intersect are a widowed artist honeymooning with his second wife, a gay man traveling with his son and his lover (and hiding each from the other), a snobbish couple from Milan who have been forced to share a suite with a pair of crass Romans, etc.
Unfortunately the movie Christmas Vacation '91 is not yet available on HBO Max.
