The M18 Hellcat

We go to the Tank Workshop in Tooele, Utah where a crew of dedicated restorers race to finish a very special project. Their boss, Karl Smith, has gathered the largest private collection of World War II vehicles in the United States, and he's throwing a VE-Day party with a big surprise. The crew has discovered that one of the M-18 HELLCAT Tank Destroyers in the collection is the same machine that a local veteran served in during the Second World War. They have two weeks to tear it apart, install a new engine, and get it running so they can take one very surprised veteran for the ride of his life.
