The low-budget, direct-to-video thriller Jekyll + Hyde updates Robert Louis Stevenson's seminal 1886 novel to the Twenty-first century. Jeff Roop and Bree Turner star as medical students Jay and Mary, whose undying experimentation with an ecstasy-like drug yields a complete loss of behavioral control, followed by a sudden descent into unbridled madness, and Mary's death. As Jay begins to gradually alter the formula with the hope of saving himself, he instead becomes more and more controlled by the substance, with little recognition of the extent to which it is reshaping his life and personality. Meanwhile, he captures the entire experience on a series of video diaries that will tell the tragic story to the rest of the world.
