Anndra comes across a lone stranger out at sea, though her true connection to the island is unclear. Isla is keen to take things to the next level with her potential suitor.
Jo threatens Pòl and forces him to help her, unaware that Ceitidh is keeping an eye on them - as well as someone much more dangerous. Cailean is willing to do whatever it takes to spend quality time with his son.
Sarah Jane learns the truth about Alasdair after she's delivered her news to a devastated Cailean, but no one is keeping an eye on wee Donnie in the garden - Things go from bad to worse for Jo and Pòl as they're finally tracked down.
The Camus community rallies together to find wee little Donnie. Sarah Jane blames herself and Cailean is questioned by the police - but the search for Donnie is dangerous and leads to a fatal altercation.
