Anna is sold by her mother for 500 US dolars to Russian gangster Arkady Karasov.
He runs a sex trafficking trade and forces her to work as a prostitute on the French Riviera.

Fifteen years later she makes a plan with three of his other sex slaves - Gina, Maria and Qiao - to take revenge and steal not only Karasov's money, but also that of his partners: Leo Imasov and Yuri.

She coerces Frank Martin Jr. ("the transporter") to help her by kidnapping and threatening to kill his father, Frank Martin Sr..

To prevent any retaliation, Anna tells Imasov and Yuri that she is working for Karasov and he has all their money in his bank account.

There is a confrontation on Karasov's yacht between all those involved, followed by a shoot-out.

Everyone is killed, except for Karasov, Anna, Frank and his father.

Karasov takes Anna hostage and escapes. Frank is in hot pursuit.

They fight each other and just when Karasov is ready to strike Frank with a rock, he is shot multiple times by Anna.
Karasov falls of the cliff to his death.

In the final two scenes, Frank is picking up his father at the police station.
They drive away to enjoy a good bottle of wine together.

Meanwhile, one month later, Anna is basking in the sun beside a swimming pool.

She got her revenge and is a wealthy woman now.

The family of her dead friends - Gina, Maria and Qiao - get 75 million US dollars each, while Frank and his father have earned ten million US dollars each.

A very successful heist. Too bad so many had to die for this.

And all the other women are still there, forced to work for the new crime lords, who've quickly taken over the sex business.
