(gentle music) (waves whooshing) - My name's Suranne Jones.

I am a co-creator, executive producer, and I play Becca in "MaryLand".

- We need to switch you.

- [Jones] Becca is ordinary, extraordinary, every woman.

She has defined herself by being a carer.

She has looked after her sister, she's looked after her mother.

She's looked after her children.

She looks after her husband.

She's got to a point in her mid forties where she doesn't know what else she is.

- I don't wanna fade into the background, Jim.

I feel like I'm disappearing.

- [Jones] Rosaline and Becca, when we first meet them, you immediately sense that they're not connected in any sisterly way whatsoever.

Rosaline is single, has defined herself by work and keeping busy and being a high flyer, and is a total opposite to Becca.

Everything that happens is devastating 'cause she didn't know who her mother was, and she thought she did.

She'd modeled her family life on her mother and father.

Coming to the Isle of Man stops Becca in her tracks 'cause she's got no one to care for.

Stops Rosaline in her tracks.

It forces both girls to take a deep look at what they knew.

- My therapist says we were forged in the same fire.

That's just therapy speak for "grew up in the same house," isn't it?

- You can live in the same house but have wildly different experiences, can't you?

- Rosaline's relationship with Becca is strained like many sibling relationships.

The closeness of Becca and their mom and them being a sort of tight-knit pair, and I think Rosaline's kind of deepest wound really is feeling like she's not in there.

She doesn't really feel seen.
