Nineteen-year-old Sid is transferred to a new prison, finding friendship with her cellmate Britt, but she also forms a complicated relationship with a guard who seems to be watching their every move. In another time, an older inmate named Kit talks to an unseen audience about a coming visitor and how she'll stop at nothing to see them, even if that means bringing down the entire prison system. In another place, three girls wait as visitors, each one thinking about the complicated positions their mothers are in. At times playful and mysterious, Guarded Girls is about the stories we tell to survive, and how the same stories can also destroy us.
