The Lincoln Lawyer will end with its fifth season, and Netflix said Wednesday that production is already underway in Los Angeles on the show’s final installment. The streamer also confirmed that the new season will bring Mickey Haller face to face with a half-sister he never knew existed.

That half-sister, Emi, comes to Haller with a plea to help free a woman who was wrongfully convicted, setting up the last chapter for Manuel Garcia-Rulfo’s defense attorney. The final season has added six actors to the cast: Amy Aquino, Angela Trimbur, Elpidia Carillo, Nate Corddry, Tricia Helfer and Keir O’Donnell.

Ted Humphrey, who developed the series and serves as co-showrunner with Dailyn Rodriguez, said the team always intended to give Mickey Haller’s story a proper ending. “All good things must come to an end, but thankfully sometimes how they come to an end is up to us,” he said, adding that the goal from the start was not only to follow Haller and his circle but to conclude their story in the right way. He said the team was grateful to Netflix and A+E Studios for the chance to “land this plane the right way” and promised that the final season is being built to deliver “the satisfying finale Mickey Haller deserves.”

The announcement comes only a short time after Netflix renewed The Lincoln Lawyer for a fifth season a week before season four premiered in February. That season went on to spend four weeks in Netflix’s worldwide top 10 for English-language series, drawing 26.4 million views in that span. In the United States, it logged a five-week run among the top 10 original streaming series measured by Nielsen and peaked at 2.54 billion minutes of watch time during the week of Feb. 9-15.

The show’s performance has made it one of Netflix’s more reliable dramas, helped by Garcia-Rulfo’s turn as Mickey Haller and support from Becki Newton, Angus Sampson and Jazz Raycole. The final season will adapt Resurrection Walk, the seventh book in Michael Connelly’s series, and the half-sister storyline gives the show a cleaner and more personal endpoint than most streaming dramas get. For Netflix, the question is no longer whether The Lincoln Lawyer can keep drawing viewers; it is whether its last season can finish with the same momentum that carried it there.
