Mensun Bound and his archaeological team rediscover the wreck of a Roman treasure ship, lost for nearly 2,000 years, a few miles off the coast of Tunisia in north Africa.

Filmmakers show the team sifting through an ancient ship stuffed to the gills with treasure - examining massive marble columns Corinthian capitals and temple entablature.

Dramatic footage reveals the lost ship’s priceless cargo scattered across the ocean’s bottom.

Digital technology also helps to recreate the final minutes of the ship’s voyage.
