Mr Happy, aka Mr Harvey has organised a School trip, the destination Salisbury Cathedral, only it isn't long before he's pushed to extremes by an unruly bunch of teenagers.
It's a brave drama, it's incredibly moving and poignant, a huge amount of depth, and some hugely touching scenes. It develops incredibly well as time goes on, the ending is incredible.
Self harm, discrimination, lots of stuff that kids say and mean without thinking about, now of course The BBC imagines such things aren't said.
If you get s chance to visit Salisbury Cathedral do so, it looks great here, nothing will prepare you for the sheer wonder of the place.
I loved David Bradley's character, the grumpy bus driver who watches all events happening with glee, he's like the perfect onlooker.
First rate acting, Spall is incredible as always, Ben Miles and Celia Imrie also. Lots of young talent on show here, including singer Jade Ewan, Nathalie Press, and Jodie Latham, who died perhaps look a little old to be in a Schoolboy's uniform.
First class drama, 10/10.
