Directed by Liv Ullman from a semi-autobiographical screenplay by Ingmar Bergman, 'Faithless' tells a story of love, infidelity and betrayal. Marianne (Lena Endre) and Markus (Thomas Hanzon) share a happily married life together, along with their nine-year-old daughter Isabelle (Michelle Gylemo), and regular visits from their good friend David (Krister Henriksson). One night, with Markus away from the apartment, David reveals his attraction to Marianne and from this one moment a dangerous and intense affair soon develops. When Markus discovers what is going on, he demands a divorce and seeks custody of Isabelle, but it is not long before he too forgoes his right to claim innocence in the matter.
