Somestimes you meet a person who changes your life forever... He's just walked into a room full of them.

Lewis is a uni-drop-out who takes a last-ditch job in an asylum working with patients who are interested in the dramatic arts. He thinks his work will involve staging a small variety show with the group, until long-term patient Roy insists that the production be nothing less than a grand staging of Mozart’s opera Cosi Fan Tutte. An ambitious thought to say the least. After all, none of the patients can speak Italian nor sing and the cast is made up of aging nymphomaniacs, obsessive pyromaniacs who really have other things on their minds. Funny, warm and wonderfully mad, COSI, based on the celebrated play by Louis Nowra, comes to joyous life with a dream Australian cast including Ben Mendelsohn, Toni Colette, Rachel Griffiths, Barry Otto, Aden Young, Jackie Weaver, Pamela Rabe, Kerry Walker, David Wenham and Colin Friels.
