Controversial but warm hearted, SWAG turns the tables on opportunists with a series of bizarre, audacious and comic hidden camera stunts. Stings include cars that fill up with foam after locking in the perpetrator, bikes that explode and a lorry that turns into a mobile cage. Regular characters include Vinnie, Fin and Bob; medieval buskers who surprise would be felons and foil their getaways with embarrassing ballads, and the overreaction squad, a crack team of melodramatic commandos primed and ready to overreact to even the slightest bad behaviour.
