Following a successful first series, which has been streamed over 2.7 million times on BBC iPlayer, Radio 1’s Sian Eleri is back diving into a new realm in the world of the paranormal – UFOs, and it all starts in a Pembrokeshire seaside village.

In the first episode, showing on Friday, June 14, it’s 1977, and 14 schoolboys from a village in west Wales make headlines around the world after they claim to see a UFO in the playground. Placed under exam conditions and asked to draw what they saw, all depict a large, silver craft with eery similarities. It triggers a wave of unexplained phenomena along the coastline.

Digging out reports about the schoolboys, natural sceptic Radio 1 presenter Sian Eleri feels compelled to find out what really happened. She heads to the seaside village of Broad Haven where it all began; her first mission to track down the boys. She’s soon in deep, managing to trace the original drawings and chasing leads on the lads. But will any of them speak to her after all this time?
