This year Kettering comedian James Acaster has been invited to turn on the Kettering Christmas lights - the highest honour to be bestowed upon a Kettering native. Now he's intent on being the best Christmas light turner-onner that Kettering has ever had. This one-off documentary follows James in the lead up to "The happiest day of my life" as he interviews previous light switchers, talks to local residents and tries to get to the bottom of last year's notorious Lindsay Lohan incident.
