Harlots of the Caribbean (2006)

Looking for a few good men

While scuba diving, Jill's boyfriend Dustin finds a doubloon necklace and the diary of Morganna, a pirate who sailed the coast 200 years ago. With the diary is a treasure map that takes them and their friends Susan and Joe to a mountain cabin. Before setting out in search of the treasure, the four hold a séance using instructions they find in the diary. It brings Morganna and her mate, Captain Tygus, back to life. It's a race for the treasure. Morganna and Tygus will stop at nothing. What about the necklace?
