CBS will ring in the new year on Sunday with a new episode of The Good Wife Season 4.

An especially dramatic episode of The Good Wife Season 4, we should say, based on the official CBS trailer for "Boom De Ya Da." It teases the removal of Will and Diane as the head of Lockhart/Gardner, as well as the return of Michael J. Fox as Louis Canning and Anika Noni Rose as Wendy Scott-Carr.

All that, and the video doesn't even give us a glimpse at T.R. Knight in the role of a rival campaign manager for Eli.

Watch now and prepare for the return of arguably the best drama on network television:
