Divers discover the wreck of an ancient Arab dhow off the coast of Indonesia. The wreck gives archaeologist Tom Vosmer a shot at a dream: to build and sale a unique replica. The quest leads Vosmer's team deep into jungles and deserts on a mission to unlock the secrets of a lost technology. But as the deadline for launch approaches, the project pushes the team to the limits of endurance; and brings the dhow to the brink of last-minute disaster.
