Emmerdale goes from “village in bloom” to boom in an explosive storyline which could lead to locals’ prize-winning plans going up in smoke.
And simple Sam Dingle gets knocked off his feet when he is caught in the blast which rocks the village as it competes for a floral title.
The explosion occurs on the ITV1 show on August 19 after he inadvertently loads a box of dynamite on to a dustbin wagon - followed later by a lit cigarette.
Villagers have put in months of meticulous planning to make Emmerdale the prettiest place in a flower contest.
After helping unload “Firecracker” Foggin’s van, Dingle (played by James Hooton) mistakenly takes a box of the explosive that was stored there.
He then takes the rubbish wagon down into the village to continue to spruce up the area for final judging.
But while it is parked up, Gloria Pollard (Janice McKensie) spots a lighted cigarette end and throws it into the back of the truck.
Waste then catches fire and ignites the box in spectacular fashion, showering debris far and wide.
A spokesman for the show said: “Poor Sam hasn’t a clue that he has loaded Foggin’s dynamite into the truck or that the excited villagers are about to come down to earth with a bang.
“Sam is blown off his feet and it looks like he could become the victim of his own folly.”
The British Queen visited the set earlier this year as part of her Jubilee tour and saw a staged explosion which was not part of a storyline.
