When cyber activists Anna and Benni publish material against the transport minister, their exploit is used to hack the ministry. While Benni just manages to escape the BKA, Anna is arrested.

Anna identifies "Rainman" as the person who could be behind 'The Last Resistance'. Together with BKA IT expert Stella, she sets out on Rainman's trail, while Benni uncovers a family secret that makes her feel betrayed.

Benni plans attacks on climate sinners with 'The Last Resistance', while Anna helps the BKA to arrest Adam. A photo on his cell phone proves Benni's involvement - Anna decides to protect her sister.

While Anna and Benni try in vain to regain the old intimacy at a meeting, Benni and Susi are finally exposed as members of 'The Last Resistance'. The BKA is getting closer and closer to their heels.

Thanks to a laptop tracker, Anna and Christoph believe they have an advantage over Benni and Susi and do everything they can to prevent the planned attack on the transport minister at the last second.
