Cameron and Nina are influenced by Jonas, an Alpha with the ability to bring its users into a blissful high until they come crashing down and eventually die. The two of them are brought to Jonas’ camp.
As more members continue to die, Cameron suggests they bring in Dr. Rosen to help save them. Rosen is able to develop a cure, but Jonas would rather cremate them and everyone in the building instead. Rosen shoots and kills Jonas in order to stop him.
