Semele died of an ectopic pregnancy, and Agave didn't do anything to help her — she didn't even believe her sister was pregnant in the first place. Now, she finds herself isolated in the cabin where her sister died, with an unusual companion to keep her company: Semele's unborn child. Meanwhile, Agave's own son, Pentheus, wants to get his mother out of his life, once and for all, despite his grandfather's advice. "Holding the Head of Pentheus" is a contemporary adaptation of Euripides' "The Bacchae", examining how grief and trauma can give birth to mythology.
