A&E’s gripping reality series about addicts and the families and friends they put through the wringer returns for a second season of intense profiles of those who have hit rock bottom and the loved ones demanding that they change — or else. People in need of redemption this season include 23-year-old Ryan, whose heroin use endangers his grandmother; OxyContin user Andrew, who has driven his family into poverty; and Amber, an alcoholic mother.
