When the Boat Comes In S04E03 - A Medal for the Argentine

Jack meets Margaret Carter-Brown, the niece of Lewis Bishop's managing director John Hartley. She is a Socialist researching the plight of the unemployed on Tyneside. He takes her to see Danny Lockhart, who is unemployed and has sold his war medal. Hartley learns that the Argentine navy want a warship and asks Jack to use his contacts to win the contract for Lewis Bishop. The deal fails, but Jack is able to win another order for an American millionaire and uses his fee to buy back Danny's medal.
