With Dr. Peter Vanguard stonewalling the police, Holly and Michael go to Safe Haven posing as a recovering addict and her brother. Once Holly discovers Thorn's secret escape route from the clinic, Michael suspects he's using it to score. Yet, when Thorn ducks out, Michael follows him to what turns out to be a rendezvous with his gay lover. Meanwhile, Michael worries that Holly's experiences with her own sister's drug overdose may make it risky for her to continue with the case.
