Happily married to paraplegic graphic designer Greg Stevens, Odelia loves her close-to-idyllic existence in Seal Beach, California, but she can't resist the temptation to visit New England once she discovers that the mother who abandoned her in her childhood is still alive and resides in Vermont. While the surprise reunion never promises to be pleasant, it is complicated by the fact that, upon arriving in Vermont during a fall festival, Odelia finally locates her mother crouching over a corpse in a corn maze (hence the title). Odelia never held an idealized view of her derelict mother, who simply disappeared from her life with no explanation, but is she a killer?
