As Above, So Below (Blu-ray)

John Erick Dowdle directs this horror thriller starring Perdita Weeks as Scarlet Marlow, a student in urban archaeology with a flair for the unusual. When Scarlet and her team discover that an important piece of history lies 370 feet beneath the streets of Paris she realises that they could potentially gain access to their point of interest through the ancient catacombs. Built in 1785 to house more than six million corpses, the catacombs consist of 200 miles of underground tunnels designed as the world's largest mass grave. As the group start to explore the passages they uncover more than they ever dreamed possible and unearth dark secrets that the mausoleum has been hiding for centuries.
