The still shows Alicia Florrick (Julianna Margulies) addressing a judge in court. While some bits from the brief synopsis were known, like the fact that Alicia will resist running for State's Attorney at Eli's (Alan Cumming) behest. But the new revelation was that something major will rock the foundation of Florrick/Agos.

Here's the brief of the premiere:
