Forced by her friends to be the first at a party to get a psychic reading, high school English teacher Sarah McCall learns more than she understands about the suicide death of her younger sister, Jenna. She dismisses the idea of a karmic agreement, that she and her sister formed a pact as souls before entering their respective lives. But, after the ten-year anniversary of Jenna's suicide passes, the reading takes Sarah on a path of reflecting on her sister's life, her own life, and their lives together tightly intertwined with baseball, oatmeal cookies, and the dream of opening a bakery.
