Garota da Moto [Russian]

Joana, a young mother who works as a motogirl, accidentally discovers a factory where refugee women are exploited as slaves. She confronts the bad guys and sets the women free, but she brings a new problem to herself. The head of the security scheme that controlled the exploitation scheme needs to prove his effectiveness after this failure. For that, he decides that he will kill Joana and whoever else is with her, so that they can serve as an example. An ambush is set up for when Joana and her son, Nico, will be participating in a collective effort at the boy's school. Joana, who is an excellent fighter, will have to defend not only her son and herself, but everyone at school from a bunch of heavily armed criminals with orders to exterminate whoever is in front of them.
