The TAG are on their way to Torquay to execute a drugs warrant, and Gary decides that it's just too boring being stuck in the van – taking the opportunity to serenade his colleagues with a hoedown – dance moves and all. Suitably entertained, they head off to the house, where cannabis is presumed to be held. Dave and Gary are on door-smashing duty, and all move in haste to avoid losing the element of surprise.
