Plot Synopsis

Executive produced by Kenan Thompson and Kel Mitchell, cast members of the original series, ALL THAT is a weekly, half-hour series that features seven young comedians, ages 12-15, who bring their own unique comedic skill to the show -- from impressions of today's biggest celebrities, to original characters inspired by their lives, to physical comedy sketches. Shot in front of a live studio audience, the first season also features musical performances from today's hottest artists, including Daddy Yankee, Ally Brooke and Kane Brown, with surprise guests from the worlds of TV, film, comedy and more. In the series premiere, the new cast is joined by original ALL THAT cast members Kel Mitchell, Lori Beth Denberg and Josh Server. Beloved roles are reprised in some of the series' most memorable sketches including Mitchell as fast-food slacker "Ed," and Denberg as "Ms. Hushbaum," the hypocritical "Loud Librarian." The episode also features a performance by Grammy(R)-nominated multiplatinum powerhouse trio Jonas Brothers of their new hit, "Sucker."
