Jeremy Green has been invited to help the shipwreck team from the world-leading Institute of Nautical Archaeology on this year's expedition. Despite a glorious past, the INA is in trouble. Unless they find a new shipwreck the future of the Institute hangs in the balance - no shipwreck, no funding. After three weeks of searching with no significant results the team receives an inspiring visit from the pioneer of marine archaeology Professor George Bass, and soon after the team discovers a large ancient wine bowl. There is now only two days remaining to find a significant wreck and the team have one more dive site up their sleeve. Will this wreck site be deemed worthy of excavation?
