Drugs, Drunks and Dogs

The Intercept team in Cornwall recruits a sniffer dog to search a suspect's car and finds drugs to the value of £2,000, and officers in Tameside, Greater Manchester, chase a driver who refuses to stop. However, the biggest discovery is in the centre of Manchester, where a raid on a huge cannabis factory leads to one of the largest hauls of its kind in the city - thousands of plants worth more than £1million.
