The highly anticipated premiere of Legion is set to air tonight on FX, but here's how you can watch it live online.

Legion has been heavily promoted for months now, due in some part to it being in the Marvel universe. The series is based on the Legion Marvel Comics by Chris Claremont and Bill Sienkiewicz about a young man whose diagnosed schizophrenia might be something more.

As FX describes it, the show stars Dan Stevens as David Haller, a man diagnosed with the mental disorder as a child and subsequently institutionalized. Aubrey Plaza plays his friend in the institution, Lenny, an alcohol and drug addict whose spirit remains optimistic. David's dull routine changes with the arrival of a new patient named Syd (Rachel Keller). Syd helps bring about the revelation in David that his visions may indeed be reality.

"A haunted man, David escapes from the hospital and seeks shelter with his sister Amy (Katie Aselton)," the FX synopsis continues. "But Amy's concern for her brother is trumped by her desire to protect the picture perfect suburban life she's built for herself. Eventually, Syd guides David to Melanie Bird (Jean Smart), a nurturing but demanding therapist with a sharp mind and unconventional methods. She and her team of specialists - Ptonomy (Jeremie Harris), Kerry (Amber Midthunder) and Cary (Bill Irwin) - open David's eyes to an extraordinary new world of possibilities."

Legion has already received rave reviews from critics, with an average score of 81 out of 100 on Metacritic.
