Buzz Kill is a light hearted look at the consequences of not having any ambition and living only in the moment rather than planning for the future. Jan has little ambition in life, he is works only sporadically and has little motivation to do anything about it. He is primarily interested in living in the moment, rather than making plans for the future. One afternoon, in an effort to relieve his boredom, he dresses in a diaper and rides a big wheel around the house. As he wrecks the big wheel on the front porch, his girlfriend, Cindy arrives home from work. Jan is pleasantly surprised when Cindy shows an interest in alleviating his boredom by playing afternoon sex games. He is soon disappointed, however, when she turns the game into something else.
