The time travellers are stripped of their celebrity status and plunged into 1588 to be servants in a great manor house. They receive a crash course in Elizabethan etiquette, deference and servitude.

In this episode, the time crashers find themselves in 1468 - the golden age of chivalry. They all take on the role of male squires in the service of two knights who will go head-to-head in a joust.

The celebrities find themselves in 1913 and they have to work as servants in an Edwardian stately home that hosts a shooting party.

The celebrities find themselves in the year 1796 and they become Georgian farm workers.

It's 1885 and the celebrities are in a Victorian fishery where they have to fulfil a huge order for Billingsgate market, but the conditions are harsh and the work is backbreaking.

In the final stop off in history, the Time Crashers land in AD 43 where they face their toughest challenge yet by creating a Celtic feast in two days before they return back to 2015.
