If you haven't seen the gripping crime drama yet then now is your chance, because the thriller is available to stream on Netflix. Jill Halfpenny (The Drowning, Dark Money, Humans) leads the cast as Kate, a police officer whose holiday with family and friends quickly takes a sinister turn when she discovers that her husband is having an affair.

The plot thickens when one of the group is found dead at the bottom of a cliff, and Kate is left determined to get to the truth.

The show is based on the best-selling book The Holiday by T.M. Logan, and stays "pretty close" to its source material, Halfpenny previously explained to RadioTimes.com.

Halfpenny isn't the only famous face in The Holiday, with fans also likely to recognise Owen McDonnell as Eve's husband Niko Polastri in Killing Eve.

In The Holiday, McDonnell takes on the role of Kate's cheating husband, Sean.

So, without further ado, read on for everything you need to know about the cast and characters in Channel 5 drama The Holiday.
