Intergalactic is set in the future where the population of Earth is governed by a global authority, the Commonworld.

The sci-fi series follows spacecraft pilot and rookie cop Ash (Steyn), who’s rising career gets cut short when she is imprisoned for a false crime. Ash will be at the centre of a high-security breakout that will see a gang of female prisoners pursue freedom across the stars.

Leading the escapees is Tula (Sharon Duncan-Brewster), a psychopathic inmate who weaponised her daughter and is now matriarch to the rest of the group, including Candy (Tomlinson), a witty convict with a good-time attitude who was locked up for her junkie tendencies, and Prisoner 99450 (Natasha O’Keeffe), a masked figure who is a mystery to the rest of the cohort.

Back on Earth, Ash’s mother, Arch Marshall Rebecca Harper (Nagra), deals with the fallout of her daughter’s arrest and the impact on her position as head of security for the Commonworld.

Elsewhere, Ash travels further from Earth and moves closer to the dangers of the other human colonies across the galaxy.

Also among the cast is Craig Parkinson (Temple), Thomas Turgoose (This Is England), Imogen Daines (Black Mirror), Oliver Coopersmith (Tin Star) and newcomer Diany Samba-Bandza.

The sci-fi drama was written by award-winning showrunner Julie Gearey (Secret Diary of a Call Girl) and will be produced by Moonage Pictures, Motion Content Group and Tiger Aspect for Sky.

Parminder Nagra commented: “I am absolutely thrilled to be part of Intergalactic and can’t wait to bring Arch Marshall Rebecca Harper to life. With the scripts, costumes, production…the audience are in for a thrilling ride.”

“I’m so excited to be taking on the role of Ash Harper,” added Savannah Steyn.

“It’s an honour and an amazing learning experience to be acting alongside such an incredibly talented cast. I’m humbled to be acting under the direction of such a wonderful team and am loving every moment of the experience.”

Eleanor Tomlinson said: “I’m very excited to be jumping years into the future to take on the role of Candy, the drug mule from the planet Skov.”

“But most importantly, there’s not a corset in sight!”

Intergalactic will be available to watch on Sky One and NOW TV in 2021.
