Sean and Adrijan are called into a case involving a woman called Joanna, who they have already had a run-in with after saving her son Ned from burning down their house while left unattended. The lads find her drunk and dangling herself from the railings of a roof threatening to jump, and must try talk her down. Although Adrijan has a rather risky method of doing so... we're worried about that fella. Elsewhere, a rattled McKay launches a second sting on Laser Byrne, but he just can't seem to get one step ahead of him, while it looks like Laser may be onto Davey, which doesn't bode well for him or McKay.
