Intergalactic is sci-fi as you’ve never seen it before.

It may be largely set in space and on different worlds, but it also explores human emotion with a dash of humour.

Find out all you need to know about the Sky Max and NOW series.

What is Intergalactic about?

Intergalactic follows Ash Harper, a young cop and galactic pilot who is wrongfully convicted of a treasonous crime.

She’s sentenced to exile on a prison planet and loaded onto a prison spaceship called The Hemlock – but after her fellow convicts stage a mutiny on board, it never reaches its destination 

Mob leader Tula Quik aims to reach the free world of Arcadia, and Ash is the pilot to get them there as they go on the run across the galaxy.
