A dashing Polish Army lieutenant named Jan Wicziewsky is in exile in the United States deep South as civil war approaches. He is faced with the question of who he really loves: the plantation owner's angry niece, Miss Regina, or the tall, blond, rugged officer who suddenly arrives at the plantation, a handsome man called Eric MacClure. (Julien Green's 1953 play "Sud" was banned from performance in the UK because of its homosexual lead character and homosexual theme. The BFI has described 'South' as the "earliest known gay TV drama" in the UK.)

Not broadcast due to a power failure, this play was repeated at S06E13.
