A new crime thriller will be airing on Channel 4 soon, which has former Coronation Street, Happy Valley and Mr Bates vs The Post Office star Katherine Kelly leading the cast.
In Flight follows single mother and flight attendant Jo (Kelly), who is coerced into smuggling drugs to keep her son safe.
The synopsis for the programme reads: "After a fight outside a bar in Sofia, 19-year-old Sonny Conran [Harry Cadby] is convicted for the murder of a member of an infamous criminal family.
"His mother Jo, a flight attendant, is blindsided by a threat to her son's life, but is then told she can keep him safe by agreeing to take on an additional role at work - as an international drug smuggler."
The programme follows Jo's attempts to untangle herself from the criminal organisation, including going to customs officer and ex-partner Domnic [Ashley Thomas] for help.
The Radio Times reports that the six-episode series is written and co-created by Mike Walden.
He has previously worked on Marcella season 3 and the detective series Whitstable Pearl, alongside Adam Randall, who recently served as director on Slow Horses season 4.
Speaking with the Radio Times about taking on her role in In Flight, Kelly shared: "Jo wakes up every morning and she doesn’t know if her son’s dead or alive. She then has to put her front-of-house face on and smile her way through the day.
Boarding passes at the ready!

"To be that polished and then to feel that edgy and raw was so appealing to me.
“As it goes on, she becomes more adept at what she’s doing, but there’s never a point where you feel like she’s on top, like she’s in control of what’s happening.
"She’s constantly failing upwards. She messes it up, then she fixes it. She messes it up and then she fixes it.”
