Plot synopsis

We originally wanted to have two men working and getting on with their daily lives but then they find a dead body at the work place. But then after we watched the footage back we thought it would look better if the scientist was behind all the murders. As he is setting up for the experiment it looks like he is about to cut up the body in the cupboard. So the rest of the film would be the builder trying to find who the killer is. The police give up looking for him but the builder doesn't stop and there are more murders throughout the film with a few twists. The scientist finds out that the builder is looking for him and threatens to kill his family too if he doesn't stop. In the end the builder finds the scientist but he gets away before the police can get there.
