On the base of the holiday Rainbow comes accountant-auditor Peter, correct, honest, principled. He refuses to settle on the basis, because the audit should be as independent as the auditor himself, especially in the housing issue.

The audit reveals the most serious violations. But the chief accountant and the director of the base are the most honest people and all their lives they have been doing the job perfectly. Where to deal with such a violation? So when Peter realizes that his audit is an excuse to destroy the base, and all documents have been deliberately changed, he decides to understand, because his professional reputation is at stake. Will he be able to save the Rainbow base from intruders?
