Marek Horn’s new drama stars two academics and an octopus. Professor Grey, a behavioral biologist, is mourning the death of her husband, who was also her research partner. She’s left with Frances, the octopus they studied together. When an ambitious young anthropologist enters the lab, romance kindles. Between meditations on the nature of animal consciousness, they flirt and fight. Jemma Redgrave (Vanessa Redgrave’s niece) stars as the grieving professor. Ed Madden, Horn’s longtime collaborator, directs the intimate production. —Jensen Davis
