Keeping Faith (2017)

Eve Myles plays Faith, a solicitor on maternity leave whose husband vanishes, and she carries the whole thing with frayed, funny warmth. It was filmed in both languages at once and aired first in Welsh as Un Bore Mercher, "One Wednesday Morning." The English version became the most popular show on BBC Wales in more than 25 years and a huge iPlayer hit, and it's the natural choice for most viewers. Much of the fictional town of Abercorran was shot in Laugharne, so the Carmarthenshire estuary is almost a second lead. Three series in all; the first is the tightest.
