World War II rages on, and secret agent Amy Smith is sent on a mission to infiltrate a Nazi base and uncover a terrifying new weapon developed by the SS.

Posing as an ally to Obersturmbannführer Hans Gruber, Amy must use her charm and intelligence to gain access to crucial information about the U-boat weapon.

Amy encounters Captain Elsa Schneider, Gruber’s trusted lieutenant, and finds herself navigating the dangerous dynamics between the Nazi officers.

As the experimental U-boat prepares to launch, Amy realizes the full extent of the weapon’s destructive capabilities and the importance of her mission.

Unfortunately, Amy's cover is blown, and she is captured by the Nazis, who will stop at nothing to extract information from her about the Allies’ plans.

Amy must find a way to escape and warn the Allies before the secret weapon can be used, but time is running out, and the Nazis are closing in.

And they are coming with full force.
