What's the story of Babylon Berlin in the third season?

The third season of Babylon and Berlin is a TV series directed by tom tykwer. The plot of the new season follows the second season, and the background is set in the 1930s. When the sound film conquered the big screen, many filmmakers were abandoned by the times. After a superstar was found dead, special agent Ratt and assistant agent Charlotte discovered a huge conspiracy hidden behind them in a series of subsequent murder investigations.

At the same time, in another murder incident that sensationalized the whole country, Root and Charlotte also tried their best to help Greg who was being used to clear up his grievances and restore the truth, but they were involved in the struggle between the two political factions, with inner entanglements, the temptation of promotion, the hardships of life and the threat of life, and they woven a game of cowardice and courage, truth and sin, persistence and compromise.

On the one hand, it is a party every night, and on the other hand, it is poor, dirty and miserable. This is the soil that breeds desire and the purgatory that loses oneself. The play adopts the form of multi-line narration and successfully shapes the group images of people of different classes. Through this Weimar and Ukiyo-e painting, we can see the ups and downs and struggles of small people in the times.
