Hold on tight, Good Wife Fanatics.

We're about to embark on a very bumpy ride.

While photos from the September 29th premiere depict Alicia at work, seemingly content at Lockhart/Gardner, we all know how Season 4 concluded: with this new partner agreeing to abandon her current firm for one she'll head up with Cary.

How will this news go over with Will, who has shared his bed with Alicia, along with his professional expertise and continually supported her at work? Not well. To say the least.

In an explosive new promo for The Good Wife Season 5, we witness Will's reaction to Alicia leaving, while also learning of Peter's plans to renew vows with his wife... while trying to avoid sexual temptation at work.

Head over to Entertainment Weekly now for the promo, which teases the confluence of politics, controversy, commitment and passion. In other words:

Everything that makes The Good Wife great.
