"THE MICK" follows MACKENZIE, aka “MICKEY” (Kaitlin Olson, “It’s Always Sunny in Philadelphia”), a brash, two-bit hustler from Rhode Island who must assume guardianship of her sister’s three high-maintenance children.

As irresponsible as Mickey has been her entire life, she may discover that responsibility isn’t the buzzkill she always thought it would be.

The series also stars Sofia Black D’Elia (“The Night Of”), Thomas Barbusca (“Middle School: The Worst Years of My Life”), newcomer Jack Stanton, Carla Jimenez (“Last Man Standing”) and newcomer Scott MacArthur.
