In a hidden corner of a London storage facility lies an ancient Peruvian mummy that has hardly seen the light of day in almost 100 years.

For the Mummy Investigation Team the position of the mummy proves to be the starting point of a thrilling case – one which challenges our preconceptions and proves that certain legends just might be true.
