Common Criminal (S03E09)

Charlotte Myddleton, a high-society 'it-girl', finds herself serving a year in Larkhall for drug-related charges. The other inmates are far from welcoming, especially since she looks down on them in her designer clothes. Meanwhile, Josh has started his role as a prison officer but is taken aback when he sees Crystal back in Larkhall, having been framed by Shell. Di manipulates a drugs test to get Crystal into trouble, hoping this will push Josh away from her. Buki spills the beans to a newspaper about Charlotte's drug talk, which is true but masked by Di swapping the test results with Crystal's. In a contrast to the prison drama, Shell and Denny are enjoying sun-soaked days on a boat in Spain, leaving everyone wondering if they’ll ever return.
