Gilda Peterborough has always worried about her twin, but when Pete deletes his Facebook page, she is doubly concerned. Pete, A.K.A. Philippa, A.K.A. Phil, is intersex, and Gilda credits all of Pete’s social problems with this biological fact. As far as Pete is concerned, however, the problems all lie with Gilda, who is constantly on his case for reasons that are unclear to him. Meanwhile, Pete and Gilda’s mother Beth frets about both of her twins, neither of whom seem to be thriving. Beth tries desperately to be a patient and laid back parent, but when Pete abruptly decides to move away from Edmonton to Montreal, both Gilda and Beth are separately compelled to try to find him and somehow reconcile the family’s unresolved past, a family history haunted by the influence of Ralph Peterborough, a father who has never accepted his child for who they are.

Events in Edmonton and Montreal spiral with the dual reckoning of Beth in one city and Pete and Gilda in another, but ultimately Beth, Pete and Gilda will have the final say in their relationships and their identities.
