Identical twins Gillian and Melina Lloyd hadn't switched identities since they were children. Gillian is in commercial real estate and Melina is a publicity handler/escort. Neither is married, but Gillian has recently decided to use artificial insemination to become pregnant. That night, after going through the procedure at the Waters Clinic, Gillian decides to throw caution to the wind. Melina is supposed to escort famous NASA astronaut, Col. Christopher Chief Hart, to a guest appearance that evening. Knowing that Gillian is a fan, Melina suggests they switch places. It seems like harmless fun until Melina is informed by the police that Gillian has been murdered. It appears that someone didnt like Melina/Gillian having a relationship with Chief Hart.
