In Chase of Being Happy (2009)

The heroine of this story is provincial beauty Katya, who works at the local grocery store. A responsive and sensitive young woman lives with her mother and little daughter Daria. Katya's husband died of an overdose, and this was not an isolated incident - a heroin plague captured the town. That's why Katya is horrified when she finds out that drug deals are being made right under her nose, and Ruslan, the owner of the grocery store, sells heroin, and the real drug dealers in luxurious cars come visit him every day. Once Katya overhears Ruslan's conversation with drug dealer Phil, and goes straight to the police. Young sergeant Stepan, long and hopelessly in love with Katya, honestly takes her evidence and reports to his superiors. What he doesn't know is that they are in conspiracy with the dealers, who keep the whole district in fear. Now Katya is forced to flee to Moscow to seek help from the capital's law enforcement defenders .
