Gasoline

A mysterious group called The Committee is prying teens from their homes and forcing them to take special tests to see who will survive and who will die.

For some odd reason, they only test two subjects at a time. One boy and one girl.

The two are never supposed to know each other. If one of them dies, so be it. The surviving one wins, and therefore is released back into the city.

They are then branded with a number.

It starts out slowly. The circuits, they aren't painful as they embed themselves into your skin. But eventually, you start to lose control.

You seem more robot-like than human now.

The humans are being turned into machines.

When a small group of teenagers that survived the Trials escape the confinement area before the Branding, they must get to the bottom of who exactly their city is being governed by...

And what their motives are for destroying all of humanity.
