GTA V: Hitchhiker: Sonny's Daughter

Sonny's Daughter is about to be buried alive if you don't intervene. 

This Hitchhiker is pretty must on the most northern point of the map at Paleto Bay. There are two guys with guns about to kill her. If you save her she will thank you and ask you to take her back home to Vinewood. On the trip, you find out she is Sonny's daughter. She promises that when she gets back she will make sure you are compensated properly.

Can you take her to Altruist? Yes.

If you don't, she will thank you and later you will get wired $60,000.
