Torn Ticket II, the only student-run musical theater group at Tufts University, presents the first of two performances of “Jekyll & Hyde,” its spring mainstage show. This dark and thrilling musical follows Dr. Henry Jekyll, a brilliant scientist whose experiments to separate good and evil unleash his terrifying alter ego, Edward Hyde. As Hyde’s violent reign spreads through London, Jekyll struggles to control the monster within him, endangering those he loves. With a sweeping score and haunting themes of duality, desire, and destruction, this gothic tale brings Robert Louis Stevenson’s classic story to life in a powerful and unforgettable way. Tickets are free and may be reserved through the Tufts online box office. The second performance will be at 7 p.m. on Saturday, March 29, also at Cohen Auditorium.
