1792. Kapitein Collier en zijn crew zijn door het Engelse hof naar een klein kustplaatsje gestuurd om daar op zoek te gaan naar smokkelaars. Tijdens zijn onderzoek ontdekt hij de mysterieuze geesten uit het omringende moeras. Collier vermoedt dat de smokkelaars bende hier achter zit en dat de iets te vriendelijke dominee Blyss er meer van af weet.
Nee, helaas is Captain Clegg nog niet beschikbaar op Netflix in Nederland.
