Anew crime thriller arrived on our  TV screens on Tuesday night, and viewers are already “hooked” after the “gripping” opening episode.

Titled In Flight, the Channel 4 series stars Katherine Kelly as single mum and flight attendant, Jo Conran, whose life is upended when she is blackmailed into drug smuggling after her son is imprisoned in Bulgaria for a murder he swears he did not commit.

You know you’re in safe hands when it comes to Katherine Kelly. Since leaving Coronation Street in 2012, the actress has starred in a string of critically acclaimed shows, from Mr Selfridge and Happy Valley to The Night Manager and Mr Bates vs The Post Office. I’ve been a big fan of Katherine since she played lovable ex-con Becky McDonald in Coronation Street, and have always found her performances captivating. It’s no surprise that viewers are loving watching her in In Flight.

What is In Flight about?

Set against the fast-paced backdrop of international air travel, this high-octane thriller follows flight attendant Jo Conran, who is coerced into using her job to smuggle drugs by criminal gang leader Cormac.

The synopsis continues: “As Jo becomes ensnared in the murky underworld of corruption and hired killers, she is forced to carry out their orders while desperately trying to find a way out. She turns to her ex, Dom, for help however, no matter how far Jo finds herself from her old life, her mission remains the same: to keep her son alive.”

The series, which is written and co-created by Mike Walden (Marcella, Whitstable Pearl) and Adam Randall (Slow Horses, iBoy), follows Jo’s “relentless quest to protect her family while entangled in a dangerous criminal syndicate”.
