An Inspector Calls (S03E06)

The guys realize that their history tends to catch up with them. A police inspector shows up on the hunt for Moxey, while a spiteful Grainger throws a wrench into the bridge-building project. Dennis steps in to mediate, and eventually, Grainger concedes to head to Arizona. With the bridge finally finished, they have a cheeky surprise in store for Grainger! Just a reminder, the Transporter Bridge remains in Middlesbrough!
