Dom and Kay have a body to bury. They're in a mess, frightened and completely on their own. Who else knows about their mission other than Clinton?

Then they bump into fellow PCSO Pricey in a 24-hour cafe, who doesn't quite believe Dom and Kay's story as to why they are caked in mud.

The burial scene

Speaking about filming the burial scenes, Gbemisola Ikumelo said: "We had very little time because it was like summer solstice, so we had two hours of dark before it got light, and we had to shoot so much. It was effectively me jumping into a ditch doing my own stunts and then hacking off a finger. It was so much fun to just play and to be able to do it and to catch it.

"I think everyone was quite shocked that we didn't need to do it that many takes. Because I was like, 'Yeah, I'll go down the hole. Yeah, I'll hack his finger off. Yeah, I'll vomit in a ditch!' And then I came out and looked at my face at the end of it and it was just covered in dust. It was one of those moments you kind of envisage you would do when you sort of think about being an actor when you're younger."
