Episode 16: Do UFO's look like Pizzas?

The Unexplainers visit the small Welsh village of Pentyrch near Cardiff. John's hunting down a UFO, but Mike's wants to find a favourite sweet shop from his childhood memory.

When the village notice board starts talking to John in code, his paranoia grows. Are they being watched by something worse than the Men in Black?

A trip to a reported UFO landing site with some UFO hunters could solve everything. But a field full of sheep and a football field sized pizza slice only adds to the mystery.
