Set in a Melbourne mental institution in 1971, Cosi is the classic Australian comedy by renowned playwright Louis Nowra. When Lewis, a recent university graduate, accepts a job directing mental patients in a performance intended to bring them out of their shells, he gets more than he bargains for as the show the patients choose is Mozart's opera Così Fan Tutte. To make matters worse, the venue for this performance is a fire-gutted theatre with a leaking roof and faulty wiring. The cast includes a pyromaniac, a junkie, a manic-depressive, a knife-wielding romantic, a confused realist, a Lithium-addicted pianist who hates Mozart, and a stuttering ex-lawyer who refuses to take part in the production. Lewis, needless to say, is slightly discouraged by the task at hand.
