Opera in 1 Act (7 Scenes). An atomic physicist (Dr. Murry) disappears on a secret mission. His 12-year-old daughter (Meg), her 5-year-old brother (Charles Wallace), and teen-aged friend (Calvin) set out on a bizarre search for him. The whimsical characters Mrs. Whatsit, Mrs. Who, and Mrs. Which lead the children on an inter-planetary journey which they manage by “tessering,” or wrinkling, to span time and space. They reach the planet Camzotz where Dr. Murry is imprisoned and confront the horrible, over-sized brain (“It”) that hypnotizes people into having one mind. After Meg frees Dr. Murry, Charles Wallace succumbs to the power of “It,” leaving Meg to also save her brother. Relying on her own strength and courage, as well as her profound love for Charles Wallace, Meg breaks the evil spell and proves that love is the most powerful force in the universe.
