I’ve found references to this episode, but it is not listed on the Intervention Episode Guide and is not available on Netflix. And as far as I know, it has not been re-run since it originally aired in July of 2005. If anyone knows where I can find it, please let me know.
Synopsis (via tv.com): A wealthy family is in crisis and desperate to help Michael, a rage addict with a long history of violent behavior who has punched 24 holes in the walls of his father’s house in the past year. And a woman seeks help for her sister, a bulimic and crystal meth addict who was sexually abused as a child by her babysitter.
