This is a dramatization based on the true story. It focuses on a South African man who is falsely accused of terrorism (really just sabotage) against the Apartheid state, and then becomes militant after he is released.
It is a powerful story at times. But I think it focuses too much on this one person (and the white cop who is chasing him). It doesn’t do a great job of showing how bad Apartheid was in general (even for people who were not accused of terrorism), or demonstrating the strength and the power of the liberation movement.
