Shadow's of Doubt

Synopsis

A young woman, in her 20's, is framed for the murder of her academic and general rival, and as she was drugged at the time, she herself also assumes that she committed the murder. As she's in jail and overseeing her case with a lawyer, which her sister forced her to get, she slowly pieces together the evidence, day by day, and realizes she didn't commit the murder. Her lawyer doesn't notice the hints and quits working the case after a while because her rival, the one she murdered, is the daughter of one of the most influential and rich families. But she, along with 2 of her inmates and a security guard, slowly starts solving the murder. In the end, the murderer is a huge plot twist that barely anyone expected.
