After 25 years playing one of television's most beloved characters, David Suchet explores why fans have always gravitated towards the great Hercule Poirot. Suchet shares his experience of portraying the iconic detective as camera crews follow his preparations and join him on set for the final, emotional days of filming. He also returns to Agatha Christie's summer home in Devon--where he met the author's family after first being cast as Poirot--and visits Belgium to explore Poirot's roots and learn what Belgians think about one of their most famous fictional sons. Hosted by Stanley Tucci, this is a must-see documentary for all Poirot fans.
