The sudden arrival of new Detective Constable Leila Hussain sets local tongues wagging. It's clear that duty inspector Finn O'Hare knows, and that Leila is fleeing serious danger in England. It's also clear that Finn and Leila will struggle to hide the truth from Finn's nosey but well-meaning mother Concepta and seasoned Sergeant Marlene.

When a burglar claims he saw a dead woman in a farmhouse, Leila and Finn call on elderly couple Gerard and Brenda Smith. Gerard claims Brenda is abroad, but Leila smells a rat. Finn warns Leila to tread carefully, being heavy handed with a well-loved neighbour could alienate the locals.

As Leila waits to hear if Callum has blown her cover, taxi-driver Barry drives into a young woman who flees the scene of the accident. Barry's bad day gets worse when Concepta spreads rumours about his `dangerous driving'.

Leila is horrified that her `old friend' Rafid has turned up in Port Devine, but she paints on a smile and greets him with open arms. Like everyone else, a jealous Callum assumes Rafid is Leila's ex-boyfriend from England. Rafid's all smiles with the locals, but he's edgy and bitter with Leila.

It's Clint and Nicole's wedding day, but best man Finn and bridesmaid Leila are busy investigating the theft of some much loved `therapy sheep'. Finn's 15-year-old daughter Niamh is back for the wedding.

Former Judge Ginette Prince sent a lot of dangerous people to prison in her time so, when someone sets fire to her home, the police officers wonder if the motive is revenge. However, Ginette's been retired for years and the criminals she put away are no longer a threat, so vengeance seems unlikely.
