Rent-A-Sister 5: Justice is Blindly Incompetent.

The eccentric and terrifying director Alexia Bastien has decided that the only way to achieve "artistic truth" for her latest film is through a mandatory "Character Immersion Retreat" on her private, remote island. Cut off from the world, Drew and Chizuru find themselves trapped in a "sibling prison" of Alexia's design, where the lines between the script and reality blur dangerously.
