Chad and Brooke are former subjects who recall their experiences with rehab. Chad's career as a world class bicyclist was ended by a crack addiction. Seven months after his rehab he's been given a second chance, having joined a racing team in Italy. But his body may have been damaged too much to make a comeback. Brooke was in denial about her addiction to pills, but agreed to going to rehab following her intervention. Now her parents are visiting Brooke to see how she's doing.
