An anomaly opens in the middle of a huge car breaker's yard and a Dracorex comes through.
The Cretaceous era dinosaur is wounded which only makes it more dangerous as it tries to protect itself.
The team try to force it back when suddenly a medieval knight gallops through the anomaly on horseback, chasing what he thinks is a dragon.
He decides the modern world must be hell and his only chance to make it to heaven is by slaying the creature - this is his quest.
The team must deal with not only with a dinosaur on the loose but also a deranged mediaeval knight who is convinced he is a latter day St. George.
