McAllister acts as a decoy to catch property developer Charles Vanderbilt in the act, but is taken aback when one of Vanderbilt's henchmen lobs a grenade through the window of the stake-out flat. Hunter asks Tait and Klein to keep an eye on Vanderbilt's right-hand man, and tail him following an altercation. When Klein corners Vanderbilt's second-in-command, Jim Conrad, the ensuing events once again leave Klein with trouble looming. Meanwhile, Nixon manages to persuade Ackland to go undercover to attract the online-ad burglar, and Stamp and Kent try to identify a young boy who has found unconscious in the street, having been the victim of an overdose of ecstasy.
