The Dinka Bride
Marial had not seen the girl he had been married to for a bride-price of 80 cattle. At the time of the marriage she was with their people, the Dinka, on the flood plains of the Upper Nile in the South Sudan. Marial was studying engineering in Leeds. The problem was that, since Marial is the oldest son, none of the others in his family could marry till he was married. He had been away for four years so his family married him in his absence. This film tells the story of Marial's brief visit home at Christmas to collect Yar, his bride. It is also the story of the personal conflicts a young man must face when he returns with a western education to a traditional life in the dust of a nomadic cattle-camp.
