Het komt Francis (Bob Monkhouse) en Douglas (Alfred Marks) ter ore dat hun verre nicht Toni (Anna Karina), een kamermeisje, een fortuin heeft geërfd. Nadat hun pogingen om Toni te versieren jammerlijk mislukken, besluiten Francis en Douglas hun nichtje te vermoorden, om op die manier zelf de erfenis op te kunnen strijken.
