Anna, Mia and Ellie are best friends and hitwomen. They are suspected of a crime and kept in isolation cells now. The girls are accused of killing a guy. The judge offers them a plea bargain. If one of them confesses and tells him the details, she will be released.
Anna-I will never tell you who did it! But it wasn't me.
Mia-I have no idea what happened to that guy. I wasn't there when he died.
Ellie- Mia did it. She is a sleepwalking. She woke me up last night and said she killed that guy.
Who is lying? Why?
