- [Oliver] Daniel's journey is one that's very much been at the beck and call of Leonard for the last few years in Grantchester.

He's very much been a part of Leonard's projects, the cafe, the halfway house.

He's been on hand to help.

- [Al] Daniel and Leonard, they're running the halfway house, and then there's a new guy called Sam who's offering faith in a different kind of direction than the church does.

- The first step is to forgive yourself.

- Thank you, Sam.

- This is a circle for sharing.

- [Elliot] He's got a new forward way of thinking, and he's gathering people to sort of try and bring on that way of thinking into the wider spectrum.

- A bit different to your congregation, is it?

Daniel, come take a seat.

What are you holding onto?

- Daniel is sort of beginning to drown a little bit.

He doesn't know where he is in life.

There's so much stuff that he really hasn't, he hasn't properly thought about.

- It's okay, go on.

- I have family that for many reasons I can't be with.

- This man seems to open him up emotionally in a way that Leonard's never been able to do.

- [Elliot] Sam is somebody who shows compassion, and he shows love, and it's not complicated by a belief in a supernatural being, as Daniel is an atheist, agnostic at best.

- Wonder if I should talk to him more.

- I didn't know you needed help.

- [Daniel] Neither did I.

- [Elliot] And for Daniel, it really starts to open up loads and loads of psychological doors for him.

- My mother and father, I hurt them.

- But you love them still.

- That kind of alienates Leonard a little bit and becomes more and more apparent and there's a kinda separation that sort of grows as happens in certain relationships as well.

They've just kind of started to drift apart a little bit, and this is where Sam gets in there and sees in Daniel someone from who he might benefit.

- He's investing in our work.

- Investing?

When were you going to tell me about this?

- It's my house Leonard, my choice.

After Daniel makes a big financial decision without Leonard's kind of knowledge and that kind of spurs Leonard on to confront Sam, and Sam kind of shows his true colors.

- I think we've reached the limit.

- I'll show you what my limit really is.

- He threatened me and he's got his hooks into Daniel.

I'm worried.

No forwarding address, nothing.

This is all wrong.

And where's Daniel?

Sam's a dangerous man.
