Pantglas

Mae trigilion pentre dychymygol Pantglas, de Cymru, yn wynebu newid byd wrth i'r gwaith mawr ar yr argae dyfu'r o'u cwmpas. Symud fydd eu hynt, ond cyn hynny bydd llawer o ddwr wedi mynd dan bont eu bywydau.

The inhabitants of Pantglas, an imaginary village in south Wales, face big changes when the work on the new dam grows around them. They will have to relocate, but a lot of water will pass under the bridges of their lives before then.
