THE YOUNG OFFENDERS BBC1 Wales, 10.40pm

Delinquent idiots Jock and Connor have grown older, but not wiser.

They are given a free holiday to Colombia. All they have to do is bring back two heavy parka coats to Ireland. What could go wrong?

Well, Jock (Chris Walley) is given an eight-year sentence in a Colombian prison, and while Conor (Alex Murphy, above) does make it all the way to Cork, police find the drugs at the airport, landing him a spell at Her Majesty’s pleasure.

Conor is not having much fun in jail. Luckily his mam Mairead (Hilary Rose) knows someone who can pull a few strings, so he’s out early. She soon tries to get him on the straight and narrow.

Meanwhile, former Principal Walsh (P J Gallagher) is in dire straits because of a split with his wineloving wife, Orla (Orla Fitzgerald).

HIDDEN TREASURES OF THE NATIONAL TRUST

BBC2 Wales, 9.30pm

Cameras return to the homes and gardens of this cultural institution to follow dedicated teams who work to protect our priceless heritage.

This episode looks at two houses belonging to people who refused to live according to the conventions of their time. First is a 16-sided building called A La Ronde in Devon, built in the late 18th century for unmarried cousins, Jane and Mary Parminter.

There’s a conservation project to piece back together the Shell Gallery – a round room with walls covered in over 26,000 sea shells, pictured.

Up the coast is Kingston Lacy, the ancestral home of the Bankes family.

Explorer William John Bankes never finished his vision of Venetian interior design, selfexiled after charges of homosexual acts.

Today his priceless art collection is in jeopardy.
