Cheng, 45, a restaurant owner from China, has travelled with his young son halfway around the world to a remote village in Finland. His wife died recently in an accident, and Cheng wanted to have a break from everything by traveling with his son to see an old Finnish friend who lives on a farm in the countryside of Finland. It’s the most remote place Cheng can imagine with endless forests, thousands of lakes, a country with entire population of one-fifth of Cheng’s home town, Shanghai.

It is the summer of 1941 and the Finnish army has been mobilized along the border with Russia. A platoon led by Lt. Eero Perkola is waiting for orders to go on the offensive. The platoon receives orders for a recon mission through the wilderness around the Lieksa lake to search for possible Russian defensive positions.
