Two un-certified employees of the St. Petersburg police—Dmitry Petukhin and Leonid Kuptsov—are forced to accept an offer from a former criminal authority, and now a very influential businessman, to investigate a murder committed in his office on a private basis. Taking on this case, they still don’t realize that soon their well-coordinated professional tandem will be called upon in other convoluted matters—both criminal and privately sensitive. After all, Petukhin and Kuptsov aren’t just good detectives. They also possess a rare talent for dealing with issues in a subtly and originally “creative” way. And it’s completely not important to them who stands in their way: a hardened criminal, a fatal woman, or an official of the highest rank.
