Pirates of Tortuga: Black Flag (2001)

On a trip to the city museum, three young boys, Alex, Max and Califax discover a golden bowl - part of a legendary Aztec treasure. While examining the bowl more closely, they accidentally set off a secret time-travelling device. Suddenly the world around them disappears, and they find themselves on board an 18th-century pirate ship. There they meet the beautiful and dangerous pirate-queen Anne Bonnie and the ruthless pirate of the Caribbean, Captain Blackbeard. It's up to the boys to save Anne Bonnie, defeat Blackbeard once and for all - and, most importantly, find their way home.
