The Simpsons will air its first hourlong episode in January on Fox, with guest stars Taraji P. Henson and Keegan-Michael Key.

The episode titled “The Great Phatsby,” follows Mr. Burns (Harry Shearer) as he tries to relive his glory days and crosses paths with a mysterious music mogul. After being conned by him and reduced to bankruptcy, Mr. Burns seeks revenge on the producer with the help of Homer, Bart, rapper Jazzy James (Key) and the mogul’s ex-wife, Praline (Henson). Also in the episode, Lisa (Yeardley Smith) is courted by the richest kid in town, Smithers (Shearer) begins a perilous journey and Marge (Julie Kavner) opens an obscure boutique store.

“I just pray it won’t be the last thing people see before a Trump inauguration,” said executive producer Al Jean.

The series’ 28th season kicks off at 8 PM Sunday, September 25, on Fox.

The Simpsons is a Gracie Films production in association with 20th Century Fox Television. Along with Jean, James L. Brooks and Matt Groening are the executive producers.
