A grand mansion. An elegant dinner party. One grisly murder after another. When guests arrive at the manor, they expect a lavish retreat, but what was supposed to be a promising week soon turns into a horrific nightmare when they discover that a killer is among them. As the guests are picked off one by one, the killer toys with the remaining guests by leaving riddles, inviting them to use forensic science to solve the crimes. The party soon dwindles until there are only three remaining guests: the winner, the loser, and the killer. It's a true survival of the fittest as they scramble to find the killer first... before it's too late.
