Mörderischer Doppelgänger - Mich gibt's zweimal (2000)

His clone is a perfect replica of himself - but with one deadly difference - My name is Vincent Springer. I am 35 years old, married, with one child. I work for the Secret Service. And I have a brain tumor. At least that's what the doctors told me. That I only have a few months to live. And that they'd like to conduct an experiment on me: to clone a perfect replica of myself. Same appearance, same mind, healthy body. Think of my family, they said. And I agreed. Now my clone is making himself at home with my wife and son, and heading a special task force to guard the participants of a top-level conference. In the meantime, I've learned something that makes my blood run cold: I have no tumor, the whole thing was a set-up, a conspiracy to use me for murderous ends. My clone, you see, is not quite an exact replica of myself: they've added just the right amount of violent genes to make him a cold-blooded killer. And his target is one of the most highly-guarded government officials at the conference.
