Deciding they need to get her to safety, Alison and Rob elect to take a shortcut to the nearest village to fetch help, but the route involves having to abseil down a high cliff named "Devils Drop".

Deciding to "follow the money", the two men give chase and gun him down, allowing Alison, Anna and Ed to escape the wilderness and reach the nearby town of Annan Mor.

Meanwhile, Serbian mobster Darko, accompanied by British mercenaries Andy and Chris, travels to the area to negotiate a ransom exchange with Mr. Kidd and Mr. Mcrae on behalf of his employer.

Having been unable to recapture Anna, Mr. Kidd attempts to bluff his way through the negotiation with Darko, recalling a previous kidnapping when he murdered a young boy in Paris when his parents tried to avoid paying.

Before Alison, Ed and Anna can be transported to Inverness by the police, they are tracked down by Mcrae, who kills the officers before pursuing them through the town, which is in the middle of hosting its Beltane festival.

Mr. Kidd nearly escapes with the ransom money, but is captured by Andy and brought before Mr. Rakovic, a Serbian war criminal who is Darko's boss and Anna's father.
