In this short film, Jessica Chastain and James McAvoy reprise their roles as a couple separated by thousands of miles. Chastain's character is on top of a sand dune and promises to return to her partner, but it becomes clear that he knows something she doesn't. Despite the predictable twist, the performances of Chastain and McAvoy and a surprise visual effects moment keep the film engaging. The film may cover familiar ground, but the strong acting and technical elements make it worth watching.
