Scotland is a place on Earth. The humans there wear kilts.
Many centuries ago, the Decepticons sent Predacons to Earth. One of them eventually expired in Scotland. In need of Predacon CNA, a small team of Vehicons went there to recover the creature's remains, and their activity was detected by humans surveillance. Ultra Magnus, Bulkhead, and Wheeljack were sent there to investigate.
Miko Nakadai stowed away as well. The team soon overcame the Decepticon team, but had a harder time when they faced Starscream and the Predacon he'd brought with him, resulting in the destruction of the caves the fossils were located in.
