"Vacation for a Massacre" is yet another in the long string of (mostly Italian) films that noticeably imitate the 1972 US megahit "Last House on the Left", and this film by Fernando Di Leo is certainly one of the best. The plot is simple and familiar: An escaped convicted murderer (Joe Dallesandro) invades the cottage of a man (Gianni Macchia), his wife (Patrizia Bhen) and the wife's sister (Lorraine de Selle), and proceeds to torment this already dysfunctional trio with rape and violence.
