When a leading Soviet scientist is abducted to work on a top-secret project, he comes face-to-face with the Kremlin's new ultimate weapon--a Demogorgon! What his top-secret captors didn't count on was the resiliency of the doctor's children. While their father has been dragooned into weaponizing a monster brought back from the US, the two young teenagers are forced to embark on a harrowing and perilous journey to find him, with help from an unlikely ally: an old but extremely deadly retired KGB agent. Things are getting Stranger in Russia and all four of these characters will need to battle impossible odds in order to survive. If they survive.
