When Kay quits her corporate job to teach English at a Chicago public school, visions of changing the world dance in her head. But in Principal Principle, a dark comedy written by former teacher Joe Zarrow, Kay learns that plenty of things are broken — the copy machine, the spirits of her fellow teachers and the system. Take a peek behind the doors of the teachers’ lounge to discover the politics and people who come together to try and make a difference — any way they can.  Get $5 tickets (plus service charge) through Goldstar for preview performances of Principal Principle through mid-April.
