When Josh's mother dies in a phobia-induced car crash, she leaves two questions for her grieving family: how did a snake get into her car and how do you mourn with no faith to guide you? Twelve-year-old Josh is left alone to find the answers. His father is building a time machine. His four-year-old brother's closest friend is a plastic Power Ranger. His psychiatrist offers only a blank journal and platitudes. Isolated by grief in a home where every day is pajama day, tests the mourning practices of religions he doesn't believe in. He tries to mend his little brother's heart. He observes, records and waits - for his mother's death to make sense, for his father to come out of the basement.
