Laid-back suburban everyman Darren "Dazza" Cook loves to entertain his friends and neighbours with his weekly backyard barbecues. Unexpectedly thrust into the limelight by his boss when an International BBQ Festival comes to town, Dazza needs to sharpen up his act, so enlists the guidance of the mysterious Scottish chef known only as "The Butcher". As Dazza hones his chops on the perfect steak, his 12-year-old son Jayden is challenged to prove the dubious Cook family ancestral link, with unexpected results.

The Butcher teaches Dazza to cook 'low and slow' and together they take his passion for the humble Aussie barbie out of the backyard and into the international arena--taking on cookers and smokers from around the world, using Dazza's secret weapon--his historic rum barrel BBQ.
