The keys to Trezor, the vault of the Ministry of Internal Affairs are lost in the confusion of the 1956 Revolution.

The convict, however, finds something very different behind the vault’s door than what he expected. An exciting plot unfolds, full of unexpected twists, where nothing and no one is what they seem to be.
