Haley Bennett stars as a woman whose habit of eating dangerous objects threatens her pregnancy; complicating matters further is her husband’s domineering family, from whom she attempts to escape. Austin Stowell, Denis O’Hare, and Elizabeth Marvel co-star in “Swallow,” which marks Mirabella-Davis’ feature debut and has the makings of an unusually tense psychological thriller. Shot on location in upstate New York and NYC.
