A group of spiteful former schoolmates attempt to spend 96 hours in the same sprawling country mansion in order to collection one million pounds each in Vol-Au-Vent director John McKenzie's dark Ealing-inspired farce. The rules are simple: remain cut off from the world in their benefactor's lavish country estate for four straight days, and collect on the fortune of a lifetime. But when a member of the group drops dead under mysterious circumstances, things get unexpectedly complicated.
