The quintet intend to scale a perilous peak but an advancing storm scuppers that plan so they go looking for adventure elsewhere.
During a hike through a forest, the friends discover a Serbian girl called Anna (Holly Boyd) buried in a chamber in the earth.
No sooner have the mountaineers rescued Anna than they come under fire from kidnapper Mr Kidd (Sean Harris).
Meanwhile, Darko (Karel Roden), who represents Anna’s father, heads into the mountains with hired gun Andy (Eamonn Walker) with a suitcase containing the ransom money that should ensure the girl’s safe return.
