The Magdeburg LKA's nerves are on edge: mishaps and leaks, cover-ups and mutual mistrust as well as an unresolved rape case undermine the team that has so far been so conspicuous. The secret investigations by investigator Sunny Becker against her superior and mentor Ralf lead to his suspension. When he defends himself against the suspicions, Sunny comes under massive pressure to justify internally. Meanwhile, the sex offender Haffner, who wants to extort ransom from his ex-lover for his escape, is holding his 15-year-old son hostage. To save Marcel, Sunny and her colleague Wächter have to find the hiding place. When the LKA team suspects him to be in a high-rise building, a dangerous operation ensues.
