The couple that slays together stays together in this satirical suspense comedy about a bored husband and wife who accidentally discover that they're natural born killers. Brian and Tanya Diggs have always been the timid couple that is too self-conscious to cut loose and have fun. When therapy fails and all the passion in their relationship withers away, Brian and Tanya become convinced that they are destined to lead a life of stale repetition. But one night, when Brian becomes locked into a confrontation that calls for him to kill or be killed, he is shocked to discover that he takes great pleasure in murder. When Brian confesses his murderous crime in Tanya, the mousy housewife isn't quite sure how to react. Soon Brian is feeling better than ever, and eager to kill again. But the second murder doesn't go quite as smooth as the first, and when it begins to look as if Brian will end up on the wrong end of the knife Tanya rushes to her husband's aid. Now having officially claimed her first victim, Tanya realizes that she too has a taste for killing. Now, as the newly invigorated couple embarks on a murderous mission to rid the world of the worst that society has to offer, they realize that there's no problem a few butchers knives and a screaming victim or two can't make right.
