What is this film starring di caprio?

Leonardo di caprio stars. I think he meets a girl, who it turns out his long lost father had d several weeks before. He then meets his father, I can't remember if he knew it was his father, who offers him money to kill the girl he had met as she was threatening to go public and he could lose his high power job. He rejects, of course but his friend finds out and kills the girl. Some more **** happens I think but I can't remember. If I've dreamt it up feel free to make it
