Secrets

Alice is living in a GIANT house (maybe a mansion) with Rosemary a.k.a. Rose and Alexandra a.k.a. Alex. Rose and Alex are step sisters and are keeping a secret and when that secret keeps Alex from doing her job then something has to be done. Alice is just a roommate to Alex and Rose and is also keeping a secret from Rose and Alex that just makes their job more fun. When the FBI is hit Alice is called in, to help with the investigation even if her agency shouldn't be helping at all. There is no evidence which just makes it even harder but in the end something comes up and something goes wrong that gets Alice in trouble. When friends are pitted against friends what will happen?
