Murder, treasure, and possible mutiny are all featured in the third season of the swashbuckler television drama created by Jon Steinberg and Robert Levine, in a story set as a prequel to Robert Louis Stevenson's Treasure Island. The danger continues to rise for Captain Flint as Captain Flint (Toby Stephens) and the Walrus crew, as he falls into unexpected peril while in dangerous territory, and motivations of key crew members are questioned. Meanwhile, enemies at home plot to take the powerful pirate ship down for good. All ten episodes from Season Three are available in this collection.

This action-adventure chronicles the escapades of a swashbuckling and brutal pirate, Captain Flint (Toby Stephens), his shipmates and his rivals in the early 18th-century Caribbean. The series is a prequel to Robert Louis Stevenson's "Treasure Island," and is set 20 years before the events depicted in that literary classic. While bounding the Spanish Main and jolly-rogering across the seas, Flint accepts a young recruit, John Silver (Luke Arnold), to join his crew, while later quashing a mutiny, questing for treasures, broadsiding other pirate vessels and exchanging fire with the ships of the British Navy who have been charged with blowing Flint out of the water.
