Thirst
Ian and Aaron are driving to their father's funeral in Las Vegas. They haven't spoken in over three years and they quickly start up an old arguement. When Ian takes a nap, Aaron picks up a hitchhiker adding fuel to Ian's anger when he awakens. The brothers argue outside as the hitchhiker decides to steal their car.
Stranded on the side of the road, Ian confronts Aaron about his lifestyle and Aaron confronts Ian about stealing his girlfriend Liz. Aaron leaves Ian, walking off into the desert. Ian helplessly calls Liz for help and then takes off after Aaron.
Two days later, Liz finally shows up, but the brothers are nowhere to be found. Ian finally catches up to Aaron and the two brothers reconcile.
