Netflix has dropped the official trailer for the final episodes of the fourth and final season of Unbreakable Kimmy Schmidt.

Premiering on January 25, the remaining six episodes include a double-sized Sliding Doors-inspired episode exploring how the main characters’ lives might have been different if Kimmy (Ellie Kemper) never had been kidnapped.

In the final episodes, Kimmy is as resilient as ever but realizes that being an adult is about more than just putting the past behind her. It’s finally time for her to choose between helping her friends — Titus (Tituss Burgess), Jacqueline (Jane Krakowski) and Lillian (Carol Kane) — and helping someone she’s never put first before: herself.

Guest stars include Jon Hamm (Rev. Richard Wayne Gary Wayne), Zachary Quinto (Eli Rubin), Greg Kinnear (as himself), Busy Philipps (Sheba Goodman), Bobby Moynihan (Fran Dodd), Amy Sedaris (Mimi Kanassis), Fred Armisen (Robert Durst), Jon Bernthal (Ilan), Steve Buscemi (as himself), Kenan Thompson (Roland), Ronan Farrow (as himself) and Lisa Kudrow (Lori-Ann Schmidt), among others.

Created and executive produced by Tina Fey and Robert Carlock, Unbreakable Kimmy Schmidt has earned 18 Primetime Emmy nominations, including Outstanding Comedy Series for each of its seasons. In addition to Fey and Carlock, Jeff Richmond, Sam Means and David Miner also serve as executive producers.

Unbreakable Kimmy Schmidt is a production of Universal Television, Little Stranger, Inc., Bevel Gears, and 3 Arts Entertainment for Netflix.
