By Peter Cann and Steve Johnstone.
A young nuclear physicist from Sellafield is on an exchange trip to Chernobyl and makes an illicit trip to the evacuated city of Pripyat, which has been deserted for 20 years.
Whilst there, he is gripped by the ghostly image of a man on top of a tower block aiming a crossbow.
In spite of repeated warnings to stay away, he embarks on a dangerous mission to discover the identity of this mysterious figure.
