Ben is a 25-year-old potential genius but has a past filled with violence, homelessness, and isolation. Ben dealt with his troubles by turning to a drug called DXM. DXM is found in some cough-suppressants that, when taken at higher doses, produces effects similar to PCP (a hallucinogenic). Ben performs desperate crimes to finance his addiction.

Josh is a 22-year-old food addict who weights 550lbs. Josh's father has the same weight problem with diabetes and a history of 6 strokes at 317lbs. Josh's father does not want an early death for his son, and the whole family hopes that both Josh and Rex can support each other through an intervention to get healthy.
