'Noises Off' follows the onstage and offstage antics of a British second-rate theatre company as they stumble from dress rehearsal to disastrous final night of a third-rate comedy called Nothing On.  The play, in three acts, takes us from the final chaotic dress rehearsal to a performance near the end of the ten-week run as  deteriorating personal relationships among the cast lead to offstage shenanigans and onstage bedlam.
