The BBC have released the synopsis for episode 3 of series 6 titled “The Curse of the Black Spot” which will air on Saturday May 7th at 6pm.

The TARDIS is marooned onboard a 17th-century pirate ship whose crew is being attacked by a mysterious and beautiful sea creature, as the time-travelling drama continues.

Becalmed and beset by cabin fever, the pirates have numerous superstitious explanations for the Siren’s appearance. The Doctor has other ideas but, as his theories are disproved and every plan of escape is thwarted, he must work to win the trust of the implacable Captain Avery and uncover the truth behind the pirates’ supernatural fears – and he must work quickly, for some of his friends have already fallen under the Siren’s spell…

The Doctor is played by Matt Smith, Captain Avery by Hugh Bonneville, Amy by Karen Gillan and Rory by Arthur Darvill.

The Curse of the Black Spot is written by Steve Thompson who previously wrote episodes of Steven Moffat’s “Sherlock”.
