Thatcher and Drummond are on an overnight obbo, watching the flat of a crucial witness in a fraud case, when Drummond's teenage son Alex shows up, claiming to have caused the death of a prostitute. His life begins to collapse around his ears when his distraught son volunteers a full confession, and then threatens to jump to his death from a warehouse roof. Elsewhere, Nixon is haunted by the memory of her recent relationship with corrupt copper Cavanaugh, who gloatingly suggests that Manson deliberately let Beech escape from custody. With little evidence to prove his own innocence, Manson is forced to sit back and take the allegations being thrown at him as the DPS start a full-blown investigation. (thetvdb.com)
