No Escape 2 (2014)

"A sister's betrayal makes the deepest wound."

Using all of their sensual seduction skills, two teen sisters practice a deception of sapphic submission to their lesbian captor in order to change their fate. Faced with a dominating mistress controlling their freedom and future, they may have to betray each other for survival during the waning days of WW2 where the collaborators in the Balkans are more feared than the Nazi occupiers.
