Malcolm Gerald and Michael Davis get to their shared flat and find themselves at loose ends. They want to find some young women to have sex with, but a trip to a hip disco leaves them partnerless, so they head home. They want a sandwich, so they use an automat machine, but it doesn't work. This eventually results in their accidentally shoving a policeman in front of a car containing adulterers Anthony Steele and Jeanne Moody. Matters proceed from there with disaster all around.
There's an air of depression that overlays everything in this movie, a thorough sense of dissatisfaction with life and the world as matters ratchet forward; the young men want to do the right thing, but don't want any consequences. The lovers are unhappy with the situation, with Miss Moody preparing to go to California with her husband, leaving Steele to grumble and whine. I found myself wishing for a more moral world for this movie to take place in, but there's no sense of it, only consequences in a random universe.
