Atlantis

In a small coastal village in Wales, Bryn and Gwen learn they will be forced to abandon their cherished home in the face of rising seawater. Their crisis rekindles Gwen’s crusading spirit, cradled at the Greenham Common protests in the 1980s – a commitment inherited by her granddaughter Rhiannon. But as the years pass, their passionate activism threatens to divide mother from daughter, sister from brother, husband from wife.
