Jessica Wright’s one-act fable tells the tale of a young woman riding the rails westward during the Great Depression. She has an untreated broken leg and one valuable possession: a solid gold locket that’s coveted by everyone she encounters, including an otherwise well-meaning hobo, an unscrupulous baggage man, and a flock of “raincrows”—murderous birds intent on tearing her limb from limb. Broadly speaking, the moral of the story is that greed is destructive. But more affecting than that is the eerie sense of milieu in this Whiskey Rebellion production. Aided by homemade special effects (rag-doll marionettes, woodcut-like projections) and Jenn Romero’s haunting, rootsy score, director Aileen McGroddy evokes the unsettling atmosphere of certain folk tales.
