Willie Harcourt-Cooze has a mission to grow and produce his own chocolate from bean to bar. It's harvest time and Willie takes his family to Venezuela to oversee their first major harvest. But is the crop good enough to get their chocolate business off the ground?

But after more than a decade spent working on the farm and developing his chocolate cooking ideas, Willie is yet to make any money from his dream. He's up to his neck in debt and his family are starting to feel the pressure of Willie's chocolate obsession. The pressure is on to crack the UK chocolate market with this year's harvest.
