The pilot centers on Vince, a former cop who's now a cunning but charming low-rent lawyer who uses his street smarts to work the system for his clients while battling his own demons and wooing his ex-wife.

Grunberg will play Mark, Vince's sweet and well-meaning older brother. He's developmentally disabled as a result of a childhood accident but is high functioning. He works as the receptionist at his brother's law firm and believes Vince can save the world.
