In the insurance company ALVA, which advertises with the motto "Your partner for your security", the head of department Heiko Gebhardt is shot in broad daylight from the building opposite. A sniper in Dresden? The investigators Karin Gorniak, Henni Sieland and their boss Schnabel question the employees of the insurance company and find themselves in a web of employee intrigues and tough company politics. Cordula Wernicke reveals to them that the insurance company expects its employees to pay fewer insurance benefits. At the same time, staff will be reduced. Shortly thereafter, she finds a projectile in an envelope on her desk - an undisguised threat.
In order not to lose one's own job, there is intense bullying within the workforce and colleagues are accused of frivolously granting a bonus or offensive behavior. Rainer Ellgast also suffered from this pressure and repeatedly got into arguments with the murder victim Gebhardt because of it. Is he capable of murder? The investigators find out that the alibi he gives himself is not correct. Gorniak and Sieland also encounter dissatisfied customers and destroyed lives among ALVA customers - like Harald Böhlert, who lost his compensation after an accident at work and years of litigation by ALVA. In the fight for his rights, Böhlert is supported by Martina Scheuring, who wants to expose the evil methods of the ALVA with radical means.
But many a betrayed person turns out to be a scammer for the inspectors at second glance. When another ALVA employee, Rainer Ellgast, was shot at the ALVA Christmas party, the investigators came under increasing pressure.
