Juke boxes are sold to all the local pubs, but the main supplier makes sure that they are the only ones to buy from. They do this by having two bikers smash up any other machines. Including the one in the Aidensfield Arms that Claude's mate had installed. Nick asks Gina to help with an under cover operation to catch the culprits. Alf goes to his would be son in law's stag night where all his drinks get spiked. He ends up spending the night in a cell because he can't go home to Mrs Ventress! There's still tension between Nick and Jo.
