Mourning the accidental death of his wife and having just moved to New York with his young son, laconic police psychologist Cal Jamison is reluctantly drawn into a series of grisly, ritualistic murders involving the immolation of two youths.
Unfortunately the movie The Believers is not yet available on Disney Plus.
