Fortress (1986) (TV)

Fortress" explores a shocking concept which shows how easily a borderline between a victim and an attacker can be crossed. The children and the teacher, calm and peaceful by nature, when driven beyond their limits by the kidnappers, eventually respond with a cruelty and fury extending that of their oppressors.

After being kidnapped by four, masked men, a teacher and her students rebel by plotting against the criminals.

When a teacher and her class are kidnapped by gunmen in the Australian outback, they soon realize that the only way they will ever escape alive is if they save themselves
