Largo Winch (2008)

Billionaire Nerio Winch is found dead, drowned. An obviously suspicious death as Nerio is the founder and majority shareholder of the powerful and sprawling W Group. Who will inherit this financial empire? Officially, Nerio had no family. But he had a secret he kept well-hidden: a son, Largo, adopted nearly thirty years before from a Bosnian orphanage. The only problem is this young heir has just been thrown in prison deep in the Amazon. Accused of drug trafficking, he claims he's innocent. Nerio murdered. Largo in prison. What if these two events were part of a plot to take control of the Winch empire?
