Project 12: The Bunker (2016) on Netflix

Plot summary

Russia ran a secret scientific mission during the Cold War that, if it had succeeded, would have altered the course of history. Officials judged the work, known as Project 12, too risky to carry on, and the scientists who had taken part were to be killed. Three of them got away. The bunker where the project was kept was shut and heavily guarded, and it disappeared from view. One man now remains from the Project 12 group, the lead scientist, and he alone holds the secrets stored in that bunker. A worldwide manhunt is looking for him. Someone is paying for an operation to revive Project 12.
