The show is starring Leila Farzad, who was nominated for the British Television Academy Award for "I hate Suzie" and "Naomi" and "Mark" Andrew Buchan. The production company behind "pain" and "Family break" is co-produced by SISTER and BBC, and written by Jonathan Brackey and Sam Vincent. The show describes the connection between a pair of partners, and it is up to them to judge the so-called "right" and "wrong" in the world they live in. Leila described the show as "a new interpretation of moral stories". The story begins 19 years ago, when Leila will play "Lou Slack" as a witty policewoman caught up in a workplace investigation, while Andrew plays "Col McHugh" as a newcomer but ambitious trust from a local gang. The two met later, reached an agreement that would change each other's lives forever, and established a complex but special relationship; the deal allowed Lou to turn her career around, and then she made.
