The case is closed and class is dismissed — "How to Get Away With Murder" is ending after its upcoming sixth season on ABC.

The final season of the Shonda Rhimes-produced dramawill follow Annalise Keating (Emmy winner Viola Davis) and her students in their final semester of law school. According to ABC's description, "The deception, fear and guilt binding Professor Keating to her students prove deadlier than ever."

"HTGAWM" premiered in September 2014, joining "Grey’s Anatomy" and "Scandal" to form the Shondaland Thursday night block known as “TGIT. Davis took home the Best Actress Emmy the next year for her searing performance.

“Viola Davis made television history with her unforgettable portrayal of iconic female antihero Annalise Keating,” ABC entertainment president Karey Burke said in a statement. “I am eternally grateful to her, [creator] Pete Nowalk and Shondaland for creating and bringing to life such a smart, sophisticated and groundbreaking series that has long been an integral part of Thursday nights on ABC.”

Nowalk added, "For me, Annalise Keating’s journey has always had a clear ending. Knowing I have 15 episodes left to finish her story, and the chance to give all the characters their own killer endings, is a gift rarely given to a series creator and I’m grateful to ABC and ABC Studios for the opportunity and creative freedom.

"I am so thankful to the brilliant cast, writers and crew for dedicating themselves to the most rewarding experience of my career over the last six years. I also want to thank our fans. The only reason this show exists is because of your loyalty and enthusiasm. I can’t wait for you all to see how it ends, with twists and turns and all the craziness we love to create every Thursday night. Buckle up.”
