Invisible Sister

On Halloween, misfit Cleo inadvertently turns her beautiful and popular older sister Molly invisible when a science project goes awry. As a result, Cleo reluctantly must agree to impersonate Molly during a crucial day at school, even as they try to reverse the invisibility. By working together and walking in each other's shoes -- sometimes literally -- the sisters learn to overcome their differences and find they have more in common than they ever expected.
