As he gets worse and worse, they see no other option than to break moral boundaries. In secret they build a lab in their apartment and start experimenting - with Erik as a human guinea pig. At first they seem to have found a cure, but they soon discover that his cells show signs of unexpected side effects. They have managed to enhance the body's properties. But what at first seems like something fun and exciting turns out to be far more dangerous than they ever had imagined.
