For four friends, the waves at Llangennith - a rugged stretch of the South Wales coast - were their sanctuary: a place to escape the grind of their dead-end lives.
But today, the Atlantic has delivered more than just a swell. Bobbing in the white water are three plastic-wrapped bricks. It's the ultimate find, but the ocean rarely gives up its cargo for free. As the group salvages their prize, they quickly realise the bricks don't just carry a fortune - they carry a target.
Now, the tide is turning and the rightful owners are closing in. In a high-stakes game of finders keepers, the only prize that matters is staying alive.
