Titch embarks on a very personal build - a vintage custom motorcycle to honour his late grandfather who was a D-Day veteran and the inspiration for his own military career. Corporal William Cormack served with 45 Commando, the same regiment Titch would be a part of 50 years later. But this is more than just a build for him. Once completed, Titch wants to ride the machine over to the D-Day beach his grandfather landed on and pay his respects to the soldiers who took part in the Second World War.But before Titch crosses the channel, there's an AC Cobra in Cornwall that needs the team's attention. Its owner, Ray, has been ill with cancer and has been unable to fix an engine fault so the beautiful car has been in pieces for the past four years. Titch and the team call in to see if they can get it running again.
