Dirty Pool.

Olga, a "self-made woman" who’d rather not gain than lose, she avoids risks and contact with the criminal world and law enforcement, seeing them as interfering freeloaders. The price of her company rises when mineral water is found on Olga’s land in property. The once-infamous crime boss wants to buy the land, but Olga won't do business with crooks. First, is persuasion. Then come threats. Her partner is killed, her son kidnapped. Despite she is not going to surrender. She gains 2 allies that have nothing in common: a former associate of the crime boss and an ex-cop, who are equally tired of living the gangster laws life. The only Olga’s hope now is the allies rule - “betray no one”. Seems that both single men are indifferent to her.
