Robert Elliot
Former secret agent Robert Elliot (Coburn) will be promoted to government advisor. In order to make sure no-one will ever know about his dirty past, he has invented a very ingenious plan to get rid of his four helpers: he gets them all to unknowingly kill each other in the course of a single night.
