Plot

In Montreal, Quebec, scientist André Delambre is found dead with his head and arm crushed in a hydraulic press. His wife Hélène confesses to the crime but refuses to provide a motive, and begins acting strangely. In particular, she is obsessed with flies, including a supposedly white-headed fly. André's brother, François, lies and says he caught the white-headed fly. Thinking he knows the truth, Hélène asks François to bring the policeman in charge of the case, Inspector Charas, so that she can explain the circumstances of André's death to them both.
