MJ and Jason investigate the disappearance of a young girl following a night out with friends. Amy makes a shocking discovery about the disappearance of MJ's sister.

Jason is assaulted by an irate husband whose wife has disappeared, but after DCI Ford arrests the man, MJ discovers this isn’t the first time the wife has gone missing.

MJ investigates the disappearance of a lawyer, who seems to have simply vanished whilst playing in the park with his young daughter.
