At Sevastopol the officers on board a battleship are looking forward to its return to port when they will be allowed to fraternise with local girls.

However, revolutionaries led by the Governor of Sevastopol's disloyal valet, Boris, plan to take over the vessel.

When the unsuspecting guests arrive for the dance, the rebel crew surround and murder many of them with the now-unarmed officers.

The authorities are forced to surrender to the revolutionaries, who then indulge in an orgy of rape, murder and looting.

Her mother dies from wounds, but Marija and her father hide in a dockside tavern-cum-brothel run by Iwan's girlfriend Sinaida.

He and a group of supporters retake the battleship and launch a raid on the fortress in which the revolutionaries are holding the prisoners.

White Slaves was advertised as a "great documentary film from the Russia of the Kerensky revolution".
