Henry Wilt is a more or less failure of a teacher who fantasizes about murdering his dominant, non-attentive wife Eva. At a party Wilt is stuck to an inflatable doll and makes a complete fool of himself. Eventually, he dumps the doll in a hole at a building site. However, he has been witnessed getting rid of the doll and when his wife disappears on the night after the party, the police with inspector Flint strongly suspect Wilt of being guilty.
