Michael & Kitt are looking for a stolen substance called Alidium. After tracking a suspect to the Bedford dam, Michael is caught in an explosion and loses part of his memory. He wakes up thinking he's still police officer Michael Long.
Did You Know?
At the dam scene, when Michael notices the different colored bolts in the wall, they are in the middle of a solid panel. As he examines the panel, the shot changes and a seam appears under the bolts (which becomes a door that Michael opens). See more
I'm afraid Michael is out there somewhere living the life of a man who's been dead for two years.
