When a woman is reportedly raped in an alleyway behind the Whitegate shopping centre, Lennox and Webb rake over the CCTV footage, however they fail to find the woman captured on the footage. When it is revealed that she was lying to protect herself from her husband, a sinister cyberstalker who is dating and attacking women is discovered to be operating in Sun Hill. Ackland adopts a new "virtual" identity to trap him, but comes under the radar of a particularly annoying drunk who nearly scares the attacker off the scent. When the first obbo goes pear shaped, Ackland tries to pull together what little evidence the team have left in order to catch the attacker in the act, and organizes a second, more secure operation.
