Tight Skin 4 (1991)

On the 35th anniversary of his company, Dimitrije Pantic gets a plaque and watch as a present instead of well-deserved promotion he was hoping for. Meanwhile, his highly corrupt boss Srecko Sojic plans to ruin the company with his business partners and sell it on auction, which would provide him with money. For being a "troubled element", Pantic loses his job at the company and finds a new one as a private detective, accidentally discovering Sojic's intentions on the first day of work.
