Blood Oath.

Salim Fayad is an ordinary pharmaceutical company owner whose life is shattered in seconds when his car kills the daughter of Lebanon's most feared drug lord. Instead of revenge, the dealer makes him an offer — become his personal assassin, or watch his family die. A Lebanese thriller adapted from the celebrated Serbian series Besa, following a decent man's descent into a world he was never meant to inhabit, doing terrible things to protect the people he loves.
