Rose Marlowe is a hard-working nurse, a loving wife, and a merciless killer. Or so she says. Despite her confession, it is hard to believe that this beautiful, kind woman could have killed her vulnerable patient in cold blood. Down-on-his-luck former journalist Theo Hazel is convinced that there's more to what happened then Rose is telling, and so decides to visit her behind bars to write her story. With each new visit, he becomes increasingly sure that Rose is hiding the truth. But is he trying to free an innocent victim, or falling prey to a calculating murderer?
