Who are you [Ziam]

When the drug addiction assaults you, you act as such and you won't give up until you get what you want.
Geoff Payne, an inveterate drug consumer, dies in a car accident, and at the leadership of the great enterprise arrives Liam, his unique son.
Vexed by his father's dark death, Liam starts to question himself about it, not knowing about Geoff's addiction and when a stranger appears from nowhere he realizes that something is not alright there.
