The lads discover that the past has a habit of coming back to haunt them. A police inspector arrives looking for Moxey and a vengeful Grainger puts a spanner in the works with the bridge-build. Dennis negotiates a peaceful solution, and Grainger agrees to go to Arizona. The bridge is finally completed - but they have a little surprise planned for Grainger!

N.B. The Transporter Bridge is still in Middlesborough!
