When Nikki and Jack investigate the killing of an East End father and son, Clarissa's husband Max is brought to the Lyell Centre to help crack the case.

Nikki helps Becky come to terms with her trauma. Jack is paranoid that Clarissa will leave the Lyell Centre. Paul is in way over his head.

An anomaly opens in the middle of a huge car parts yard and a dinosaur from the Cretaceous era comes through. The Dracorex is wounded, which only makes it more dangerous as it tries to protect itself. The team is trying to force it back when, suddenly, a medieval knight on horseback gallops through the anomaly, chasing what he thinks is a dragon.
