Nashville Children’s Theatre, 25 Middleton Street, Nashville

Room 207 at Horace B. Smedley Elementary School is out of control! The teacher, kindly Miss Nelson, just can’t seem to keep her rowdy students in line. When she mysteriously disappears, she is replaced by someone . . . well, . . . louder. Stricter. And much, much scarier. In fact, Viola Swamp is the substitute teacher from your worst nightmare! Before long the desperate kids in Room 207 hire a detective to lead them on a hilarious mission to find Miss Nelson. All performances are open to the public, and reservations are recommended. Individual ticket prices are $12 per child (ages 2 to 17), and $17 per adult. Season subscriptions and group discounts are also available. A sign-interpreted performance is scheduled for Saturday, March 13, at 2 p.m. More info: (615) 254-9103.
