Invited to a human rights festival in Bangladesh as guests of honour Rupert and Jan decide to drive there in their family car - a notoriously battered 1936 Rolls Royce.
They ship the Rolls to Mumbai and motor across India to Dhaka. They fall into company with tea-wallahs and maharajahs, dodge tribal conflicts and battle border officials ultimately landing their car in the hands of the Bangladeshi Customs.
This is a rare glimpse into a uniquely inspired expedition that redefines later-life. Side by side, they drove for six months and covered over 5000 miles. Though Rupert was at the wheel, Jan quietly propels the journey with a gentle strength, and we witness their lasting love grow stronger through this incredible experience.
