The Killing Gene (2008)

A missing pregnant woman’s body surfaces, but something is not right. Carved into her stomach are the symbols “W Delta Z”. The two cops in charge of this specific case pass the entire thing off as gang violence and nothing more under the assumption that carving a message into a dead body indicates that the victim isn’t the person who should be reading it. Further investigation leads them to discover that the women in question was actually knocked out by a rare compound. But as they bring this evidence up with their small towns only scientist in possession of that compound, they spot “W Delta Z” scrawled out on his office chalkboard. After evading capture for some time, the truth comes out: “W Delta Z” represents the selfish gene concept and those with it want to protect the people they love who share their DNA in some way, no matter the cost. Someone is using this to their advantage, pulling the strings of those with this gene and forcing them to commit some of the most gruesome torture porn style murders you could imagine.
