Close People(2006)

Close People is a Russian drama series that follows three construction company partners—Stepanov, Chernov, and Belov—as their thriving business unravels under mounting pressure. When a major new project begins, a series of catastrophic events unfolds: strikes paralyze the site, a worker is critically injured, and a foreman dies under suspicious circumstances. As investigations deepen, the friends discover that each has been keeping dangerous secrets, breeding paranoia and fracturing their once-solid bond. Suspicion turns inward as they question whether one of them could be responsible for the deaths. The series explores whether their friendship can survive the weight of deception, guilt, and the hunt for a killer operating within their inner circle.
