Bannan

Three years have passed and a lot has changed in Camus, with Isla opening a new bistro with her good friend Pòl, Anndra's boyfriend. But she soon realises that money can't buy her happiness as she sets her sights on something, or someone, that money can't buy. Sarah Jane's life goes from strength to strength until a stranger from her past arrives back in Camus. He puts his own life in danger when Sarah Jane and the rest of the community shun him – everyone but Ceitidh, the only one who takes pity on him. Despite Finlay's concerns, Donna is optimistic for the future, though Iain distances himself from the family and keeps himself busy working on the estate.

Anndra finds a girl in the hull of a boat out at sea, though her true connection to the island is initially unclear. Isla is keen to take things to the next level with her potential suitor and believes she's figured out the real reason it's not moving on as she'd hoped. Donna and Finlay struggle to be honest with each other about their feelings, while Iain gets an unexpected lodger in his bothy.

Jo threatens Pòl and forces him to help her, unaware that Ceitidh is keeping an eye on them. Cailean is willing to do whatever it takes to spend quality time with his son. Jo and Isla get to know each other a bit better, though Jo's motives for the friendship are unclear – but little does she know that even more trouble lies ahead.

Sarah Jane learns the truth about Alasdair after she's delivered her news to a devastated Cailean. He is overcome by fury and no one is keeping an eye on wee Donnie playing in the garden… Things go from bad to worse for Jo and Pòl as they are finally tracked down. Iain takes a big step and finally admits what he's really feeling, reuniting with his father to try and help Donna.

The Camus community rallies together to find wee Donnie. Sarah Jane blames herself and Cailean is questioned by the police – but the search for Donnie is bloody and dangerous and leads to a fatal altercation.
