From Bill Dubuque, creator of Ozark, M.I.A. hits Peacock with all eight of its episodes at once. Shannon Gisela stars as Etta, smart, resourceful, and college-bound, who’s also a little spontaneous: maybe she’d like to stay in South Florida and work for the family business, which includes a bustling marina, tourist trawls, fishing charters, and…another, hidden revenue stream.
