The Pact is BBC One's new drama coming to television screens in May.
Starring Breaking Bad's Laura Fraser and Coronation Street's Julie Hesmondhalgh, the female-led thriller follows the mystery surrounding the death of a brewery boss and sees four women drawn into a pact of silence.
Written by Pete McTighe and made by Cardiff-based production company Little Door Productions, the new series is both created and filmed in Wales.
Scottish star Laura, who plays Anna, has also discussed the "lovely" filming first she experienced on set of The Pact.
She said: "I know this sounds like such a generalised statement but the Welsh people are the kindest, most generous people, they're so sweet!
"There's this culture at work where everybody gives each other presents all the time – I've never seen that at work.
"Usually you just get presents at the end but every week you see someone giving presents to somebody and you think 'I'll start doing that too!' and even if it's a wee bar of chocolate you bring it in for someone.
"You'd see one of the runners giving a driver a crossword book and it's just so lovely!"
