Holloway's hopes of nailing Miller take a dive, however, when his main witness is scared off. Holloway's only chance is to come up with another witness, fast.

McCall finds himself drawn to Roberts' wife, Margaret, who despite having her life turned upside down, remains defensive of her husband's actions, believing his story of self-defence.

Webb is slow in coming forward with information regarding the death of Moira Randall - the wife of the armed robber who turned in her husband to Webb in Episode 17. He doesn't want his affair with Moira uncovered. But when it is, Webb receives heavy repercussions from the Police Service and family. The Boat Crew are kept busy by a group of drunken University students on Shark Island. They're given a hand by some National Parks and Wildlife Officers, one of whom Sykes finds very attractive.

The boat crew find a distressed man on an overturned boat in the harbour. His mate has gone overboard. Goldie and Harrison start considering making plans together, as their relationship becomes more serious.

The Water Police and Homicide detectives continue to search for Chris Kollias. It's not until the end of the episode that Holloway learns of Knocker's probable involvement in Kollias' and Kevin's death. Meanwhile, Knocker and Goldie's romance blossoms, with Knocker meeting Goldie's family. When recovering a submerged boat, the divers come across a body.

Cassidy and Tavita go undercover to catch a flasher at Nielson Park.

An Asian crime racket is suspected when two dead bodies, killed by carbon monoxide poisoning, turn up in the harbour. They both have evidence of being tied up and both from an oriental background. Detective Inspector Li, an Asian crime specialist from Task Force Oak joins the Water Police for the investigation. Coming to terms with Knocker's probable corruption, Frank Holloway is given Internal Affairs' dirty work of searching Harrison's house for evidence. Goldie, however, is excited by the prospect of spending her life with Harrison, and can't believe it when Internal Affairs and Holloway turn up to raid Knocker's house early in the morning.

Goldie isn't fully aware of what's going on, but is sure Internal Affairs are conducting another misguided investigation. Goldie and Harrison investigate the case of an old man's body dumped in the harbour.

As much as Holloway and Brady try to close in on Knocker, without losing any more of their vital witnesses to Kevin's murder, he's always one step ahead of them. If Knocker manages to eliminate the last two witnesses who were at The Gap that night, he could walk free. Goldie has to face undeniable evidence of Knocker's corruption.
