Darius is a newly successful playwright, his debut a huge theatrical hit. After returning from a spell recovering from a drinking problem, he returns to Paris to see posters advertising his new play. His only problem is that he hasn't written it yet. Suffering from writer's block, he despairs of ever getting inspired. But then he accidentally kills the nighbor's cat and wakes up the next day to find the start of a play on his computer screen. Connecting death to his creativity, he embarks on a murder spree, despatching all sorts of living creatures in an attempt to finish his opus.
