Winter Kept Us Warm (1965)

It's the 1960s at the University of Toronto. Doug is a well-liked senior with an equally popular girlfriend. Peter is a shy freshman, and new to the big city. Peter and Doug become best friends and soon start going to concerts, drinking, and playing in the snow together. When Doug brings Peter to a steam bath and washes his back, the friendship seems headed to a whole new level, at least in Doug's mind. But when Peter emerges from a party after having sex with a co-ed, things get even more complicated.
