Ellen Pompeo is making the move from ABC to to Hulu.

According to The Hollywood Reporter, the Grey’s Anatomy star is set to star and executive produce an untitled orphan project for Hulu. The project will be her first on-air series through her production banner Calamity Jane, which has deal at ABC Signature.

Pompeo’s Grey’s Anatomy role will be shortened to only eight episodes in the 22 episode 19th season. She will still be on board as the shows primary narrator. Despite rumors, the actress is expected to return for future seasons of the show.

Hulu says the drama is “inspired by the story of a Midwestern couple who adopts what they believe is an 8-year-old girl with a rare form of dwarfism. But as they begin to raise her alongside their three biological children, they slowly start to believe she may not be who she says she is. As they question her story, they’re confronted with hard questions of their own about the lengths they’re willing to go to defend themselves, falling into a battle that’s fought in the tabloids, the courtroom, and ultimately their marriage.”

In addition to starring, Pompeo executive produces alongside her Calamity Jane production company exec Laura Holstein. Katie Robbins (The Affair) created the series and serves as writer and EP. Erin Levy (Mad Men) serves as showrunner and exec produces. Mike Epps, Dan Spilo, Niles Kirchner and Andrew Stearn serve as non-writing exec producers.
