Whilst the mermaid celebrated another successful launch, its future hangs in the balance at a London court. The mysterious disappearance of lovelorn Lynne causes panic.

Brittle Polly Urquhart is delighted by the arrival of American stud Orin. Lynne's amnesia leaves her living in a world of strangers and news from France threatens Tarrant's bourgeoning fashion scene.

Environmentalist Leo comes to blows with creepy Ken Masters over the development of a local beauty spot. Patriarch Tom resorts to desperate measures to hep Lynne.

As leather-clad Leo mourns for the birds, Mr Shellet plots a dangerous revenge. Ken's ambivalence towards Claude's designs enrages dazzling Jan and silver fox Charles puts a scheme in motion.

Lynne’s transatlantic venture drives a wedge between Tom and Jan. Resistance to the marina development gathers momentum and Jack delivers Shellet an ultimatum. 

There’s concern across Tarrant as Lynne disappears from radar. Abby’s mothering abilities are called into question and the press get wind of swanky Charles’s plans… 

Ken’s cloak-and-dagger attempts to frighten Leo don’t have the required results. An opinionated visitor forces an impossible decision on Abby and an affectionate gesture from Tom emphasises Jack’s increasing distance from the yard. 

Polly’s revelation leaves fertile Charles in a quandary. Jack’s behaviour causes concern at home and the boatyard, forcing wily Avril into a boardroom decision. 

The old firm is back in business, Bill!” Gerald forces a reconciliation with Charles. Abby’s involvement in the local environmental group causes concern for Leo and Jack agrees to a controversial commission. 

Oh, happy day! France and Britain are joined in matrimony. Charles’ interests in the Mermaid ruffle feathers in the boardrooms of London and Abby confuses politics with desire. 

Darling Jan proves she’s as wonderful a daughter as she is a mother and lover. Charles finally gains control of the boatyard, but is it just business he’s after? What future is there for the Mermaid when tragedy strikes the Lynnette? 

Charles and Abby come to a resolution. Claude’s designs dazzle the London Fashion Show, but hearts break and blood is spilt on the beaches and blouses of Tarrant.
