In this special programme Guy Martin, takes a rare week off work for a deeply personal crusade: to journey to the Baltics and uncover the truth about his late Latvian grandfather, Walter Kidals. The exact details of Walters early life have always been unclear and so Guy decides to find out what really happened to his grandfather. Driving a 30 year old Lada Riva around the Latvian countryside, Guy discovers the site of his grandfathers old home and school. Guy uncovers an extraordinary World War II tale involving forced conscription into the German army and witnesses a full scale battle re-enactment. Guys trip finishes with an emotional reunion with his long lost Latvian cousins. The journey wont just help paint a picture about his grandfathers life, but it will also provide some answers about the origins of Guys own unique personality.
