Immortals (2017)

Despite being forever stuck at age 19, Riley has lived for over a century, her Immortality as much a gift as it is a curse. She yearns to escape her isolation and loneliness for a simple life, but discovers that she is part of a long lineage of Immortals who have lied to her regarding her origin and importance. Now, hunted by her own, Riley will abandon everything she's ever known, and set in motion a chain of events that will threaten their very existence.
