After the funeral, Alan's brother-in-law Doug Billings informs friends Phil Wenneck and Stu Price that Alan has been off his Attention deficit hyperactivity disorder medication and is out of control. The group attends an intervention in which Alan agrees to visit a rehabilitation facility in Arizona where he can seek treatment, as long as "the Wolfpack" takes him there. On the way to Arizona, Phil's minivan is rammed off the road by a rental truck and the group is taken hostage. They are later confronted by mob boss Marshall and "Black Doug", his head enforcer.
