Last month it was announced that The CW has given the green light to a pilot for a reboot of Roswell, and now Deadline brings word that Jeanine Mason (Grey’s Anatomy) has been cast as the show’s lead.

Mason will place Liz Ortecho, a jaded biomedical researcher and the daughter of undocumented immigrants. Reluctantly returning to her tourist trap home of Roswell, New Mexico, Liz “is haunted by a tragic incident. She discovers a shocking truth about her teenage crush who is now a police officer: He’s an alien who has kept his unearthly abilities hidden his entire life. She protects his secret as the two reconnect and begin to investigate his origins, but when a violent attack and long-standing government cover-up point to a greater alien presence on Earth, the politics of fear and hatred threaten to expose him and destroy their deepening romance.”

Based on the Roswell High book series by Melinda Metz, the new series has been written by Carina Adly MacKenzie (The Originals), with Julie Plec directing. MacKenzie and Plec also executive producer alongside Kevin Kelly Brown, Lawrence Bender, Justin Falvey and Darryl Frank.

The original series of Roswell premiered in 1999, with the show running for 61 episodes across three seasons.
