[1] The events of the episode begin with Superintendent Adam Okaro and Inspector Gina Gold trying to track down PC Andrea Dunbar after her exposure as an undercover journalist, unaware she was meeting with her lover, DI Neil Manson.
Both were mortified when they discovered that she had been exposed, and as they met again at court ahead of Alan Kennedy's trial, Manson dumped her and accused of her being two-faced, asking if her apology was on or off the record.
Back at Sun Hill, DCs Ken Drummond and Jim Carver interviewed the Meghan brothers, under suspicion of running a credit card cloning operation.
At court, Alan Kennedy's QC Michael Sherwood (Jonathan Coy) tore Andrea apart on the witness box, causing the case to fall apart.
Colin set out to drive into the front of Sun Hill to prove his comments about terror attacks were justified, and despite Ken's protests, he refused to back down.
Alongside the Sun Hill police officers and detectives, several non-policing emergency services including the fire brigade and ambulance were at the scene of the explosion.
As the evacuation of all the police officers, detectives and the two male Asian suspects ensued, Gabriel began to feel guilty and tried to head back for Andrea, and he panicked after Supt.
Back at a local community centre where the officers from Sun Hill were, DC Jim Carver discovered his wife, Sergeant June Ackland, was cheating on him with PC Roger Valentine.
When the arrests were picked up, Jim told June the recent deaths of Ken and his ex-wife Marie, on top of her affair, was reason enough for him to leave London.
