The ABC Murders (2018)

A freediver and wildlife photographer studies puffins on the Pembrokeshire coast, using specially designed headgear to get as close as possible to the birds, as well as exploring the kelp forests that lie beneath the surface in St Brides bay. In Snowdonia, an upland sheep and cattle farmer prepares his prize bull for the auction ring, and In the Brecon Beacons, father and son paragliders attempt a launch off Hay Bluff.
