After a stranger contacts her on her laptop, Emma Becker is amazed to discover that she has an identical twin, Sutton Mercer, and they were separated at birth.

While impersonating Sutton, some of Emma's personality emerges to the delight of Sutton's family. Emma takes dance lessons in order to please the father she never had.

While Sutton meets the woman who signed the twins' birth certificate, Ethan accepts an invitation to dinner.

Sutton and Emma are surprised to discover commonalities between their dreams and encounters throughout childhood.

Emma realises that she is no longer living Sutton's life but living the one she has always wanted for herself.

Emma and Ethan's kiss has a backlash; Sutton may have gotten closer to learning where Annie Hobbes has been.
