Dean and Sam will deal with a case involving German dictator Adolf Hitler in the upcoming episode of "Supernatural" season 12.

In the previous episode, the Winchester brothers investigated a case involving a religious family and their daughter named Magda, who was kept in the basement of their home. Later in the episode, a member of the British Men of Letters killed the daughter so as to clean up the mess the Winchesters got into.

The upcoming episode will follow the Winchesters as they prevent Adolf Hitler from being resurrected. Based on the synopsis for the episode, the two will learn that the soul of the German leader is trapped in a 1930 gold pocket watch. Upon learning this, a group of Nazi necromancers will seek to resurrect the Furor. The mission of the two brothers is to act quickly to stop them.

Aaron Bass, who helped Dean and Sam stop Nazi necromancers in season 8, will return in the next episode to help them again with the Thule Society. This society is a group of Nazi-loving necromancers who have a master plan to resurrect the German dictator. It can be recalled that in season 8, Aaron was introduced as a member of the Judah Initiative who helped the Winchesters thwart the mission of the Thule Society.

The trailer for episode 5 shows Dean itching to use his grenade launcher in order to destroy the pocket watch, which is allegedly where the soul of Hitler is trapped.

"Supernatural" season 12, episode 5 airs on Nov. 10, 9:00 p.m. on The CW.
