Der Fürsorger(2009)

Caregiver Hans-Peter Stalder knows the secret code to happiness: a money multiplication strategy that promises hand-picked investors almost unbelievable profits - and a carefree life of luxury. There's just one catch to his story. It's a hoax and only one person stands to benefit: Stalder. For thirteen years, the notorious conman and womanizer fools his naive victims and the authorities.
