Blood Knot looks at the ties between two brothers during apartheid. One has white skin, the other, black, born to different fathers. Morrie wants to take Zach away from their township shack, buy a farm and start a new life and to take their minds of his struggle, they decide Zach should have a pen pal. But as things start to go wrong, can the two boys free themselves from the enduring prejudices that surround them?
