Exodus is a company specialising in disposal... of your loved ones. Vincent works as their professional 'suicide merchant' but has perhaps taken on his final job when turning up at the Bryce mansion with a poisonous potion. Has he been engaged by Walter Bryce to "do in" his wife Celia so he can run away with his mistress? Or has Celia employed his services to fulfill her bizarre double-suicide pact with Walter? A series of unsigned suicide notes only adds to his confusion. Every time he thinks he has it right, a rubber plant is the only victim of the multiple-poising attempts. Will Vincent succeed in killing anyone?
