A Run for Your Money is a 1949 Ealing Studios comedy film starring Donald Houston and Meredith Edwards as two Welshmen visiting London for the first time.

Then the two miners become separated when Dai is picked up by attractive con artist Jo (Moira Lister) after she overhears them talking about the prize money.

As they spend time together, Dai begins to fall in love with Jo, though he already has a girlfriend back in Wales: Bronwen, the boss's secretary.

Meanwhile, Twm recognizes a familiar face: Huw Price (Hugh Griffith), a down-on-his-luck harpist and traditional Chief Singer with whom he had once won the grand prize at an important Welsh music festival.

Dai proposes that she move to Wales and offers to give her money to pay for the fare, but then he remembers Bronwen and changes his mind.

Dai gets Jo's purse, with the money in it, and runs to catch the train back to Wales, where he is reunited with Twm and Huw.
