Until, that is, they meet Severin Winter, Professor of German and wrestling coach, and his delicate wife Edith at a faculty party. Utchka and Severin are rather taken with one another, and, conveniently, their spouses appear to be similarly smitten. A bizarre menage a quatre is the result of these convoluted desires, and what starts out as a bit of fun is soon subject to the darker machinations of obsession,.
