Murder. It's a relative thing.

Joe and his siblings have a couple of problems. First off, their stepparents are despicably evil. Secondly, they seemed to have killed them. Now this mixed up mess of half-sisters and step-brothers have to figure out how to dispose of the bodies, cover up the murders, collect their grandfather's inheritance and somehow stick together as a family -- all without getting caught. Not to mention Joe's incessant need to keep tabs on his promiscuous sister, an eye on the precocious little ones and a lustful watch on the girl next-door. Growing up has its complications. Murder's just one of them.
