Dahmer Vs Gacy -- A government experiment has cloned serial killers to create super soldiers. Naturally the titular murderers get loose & go on a rampage. The only hope to stop them is a madman who talks to God. None of this is meant to be taken seriously but the gore does flow. Sick horror comedy (necrophilia/cannibal jokes) but if you like black humour it's primo.
