Two Brazilian sailors prepare for a transatlantic voyage that will change their fortunes forever in ways they can’t imagine. Daniel and Rodrigo sign up for a life changing opportunity to crew a yacht from Brazil to Europe and gain the experience they both crave. But before they even set off, police and their sniffer dog raid the boat and spend hours searching for cocaine, which they think may have been hidden on board.

Daniel and Rodrigo’s dream voyage soon becomes a nightmare. Days into their Atlantic crossing, the boat’s motor stops working, one of their crewmates becomes too sick to get out of bed and cabin fever sets in. They’re forced to make an emergency stop in Cape Verde, the archipelago of islands off the coast of West Africa known for its natural beauty and its beaches. But they don't get the welcome they’re hoping for.

The sailors are imprisoned in a country known as a “motorway service station” for cocaine cartels. Among certain police forces and crime agencies, the shortest sailing route from Latin America to Africa is known as drug traffickers’ Highway 10. Cape Verde lies at one end of it.

The West African nation is used as a handy stop off point for smugglers to refuel or swap boats ahead of their journey on to Europe. For Daniel and Rodrigo though, it was somewhere to enjoy the beaches and the surf. But they can’t do that now they’re locked up in jail.

Colin and Yemesi learn more about the wider destructive impact of drug dealing and the international narcotics market, boarding a police boat as local cops patrol the ocean.

A police chief in Brazil investigates Fox. He spends months overseeing surveillance of Fox’s yacht, then months more investigating how more than a tonne of cocaine ended up on board.

For Andre Gonçalves, it begins with a tipoff from Britain’s National Crime Agency. He’s determined to fix what he sees as a grave injustice for the sailors after their arrest and harsh sentencing.

Colin and Yemesi track down Fox's former crewmate, fresh out of a Brazilian jail and seemingly ready to talk. He travelled with Fox to Brazil on the Rich Harvest yacht and spent months there overseeing the first stage of its renovation, before the police raid and the arrests. So what can he tell us about his former employer? And what does he say about the drug smuggling and the sailors?

Our investigation moves to a hotel car park in Norwich, England. What more new leads will this bring? We find the man himself, but what does Fox have to say about the tonne of cocaine found on his yacht? How does he respond to the claims from Brazilian police?
