Gabe Dumas and Dave Cortez are officers in the Mech Enforcer Division of the NYPD. If Gabe wishes they did more than work together, well, that's his problem. He'd rather have him as a friend and partner than nothing at all, and there's no one better to have at his back when the streets get ugly.

During a raid on the Diamondbacks, a notorious and dangerous gang tearing up the city, everything goes sideways and it's Gabe who comes out the worse for it. Furious, devastated, Dave is determined to have revenge on the men who nearly killed Gabe.
