'Try this tequila oil, Hugito. Just as the alcohol hits your stomach, the chilli will as well and blow it back into your brain. It will take your head off.' Explorer Hugh Thomson takes on Mexico.

It's 1979, Hugh Thomson is eighteen, far from home, with time to kill - and on his way to Mexico. When a stranger tells him there's money to be made by driving a car over the US border to sell on the black market in Central America, Hugh decides to give it a go.

Throwing himself on the mercy of Mexicans he meets or crashes into, Hugh and his Oldsmobile 98 journey through the region, meeting their fate in the slums of Belize City.

Thirty years on, Hugh returns - older but not necessarily wiser - to complete his journey.
