In 1918, a group of security officers removed confiscated jewelry from Irkutsk. On the way to Petrograd, the Cheka employees are faced with a serious problem: there is a rebellion in the Urals, and it is impossible to move on. There is also nowhere to return - Irkutsk is in the hands of the enemy. The security officers load boxes of jewelry onto carts and rush to take refuge in the taiga, the whites rush after them. Both detachments disappear in a remote, uninhabited area - and there are no traces... In 2006, students of the history department find the diary of a White Guard lieutenant. It describes in detail the valuables that were confiscated by the Reds, and the students are fired up with the idea of finding the treasure at any cost. They equip an expedition, go to the taiga... and soon encounter dangerous competitors there. It turns out that they are not the only ones searching for treasures...
