What is this called?

[SP1]

OK, so a month or two ago I watched ep1 of...something. Maybe I'm getting old, but I've forgotten the title, and this is making finding ep2 rather difficult.

Plot synopsis:

Sci fi plot i nfuture with many colonies. We start in a house with 3 sisters, and the youngest, who is about to be put upon to do some problem chore, steals a hovercar with the assistance of a robot (chibi) servant. She dodges all attempts by her sister to capture her and ends up at space school, which she promptly ditches in a stolen space pod.

At the same time, some huge colony-destroying ship comes out of hyperspace and the girl gets sucked up into the ship along with another woman who is some kind of detective. The girl meets up with the ship's master, a whacked AI thing that is having existential issues.

So, anyone know what this is?

Woot! That's the one. Now my life can, once again, be complete.

...well, I've only seen one episode, so perhaps completeness is a stretch.

Thank you.
