Plot Summary:In the insurance company ALVA, which advertises with the motto \"Your partner for your safety\", the department head Heiko Gebhardt is shot in broad daylight from the building opposite. A sniper in Dresden? Investigators Karin Gorniak, Henni Sieland and their boss Schnabel question the employees of the insurance company and find themselves in a network of employee intrigue and tough company policy. Cordula Wernicke reveals to them that the insurance company expects its employees to pay out fewer insurance benefits. At the same time, staff are to be cut. Shortly afterwards, she finds a projectile in an envelope on her desk - an undisguised threat. In order not to lose one's own job, the workforce is intensely bullied and colleagues are accused of recklessly granting a bonus or offensive behavior. Rainer Ellgast also suffered under this pressure, and because of this he repeatedly got into arguments with the murder victim Gebhardt. Is he capable of murder? The investigators find out that the alibi that he gives himself is not correct. Even among ALVA customers, Gorniak and Sieland encounter dissatisfied customers and ruined livelihoods - like Harald Böhlert, who was brought about by ALVA for compensation after an industrial accident and years of legal dispute. In the fight for his rights, Böhlert is supported by Martina Scheuring, who wants to expose the ALVA's evil methods with radical means. But some people who have been betrayed turn out to be fraudsters themselves for the commissioners at second glance. When another ALVA employee, Rainer Ellgast, was shot at the ALVA Christmas party, the investigators came under increasing pressure.
