Lexa is a young plastic artist who has dealt with multiple personality disorder since she was little. Two other personalities live within her: Alejandra and Sandy. Although she never knows for sure which of them will emerge, she controls them and has a quiet life.
While she is working on her new exhibition, Alejandra and Sandy meet and begin to fall in love. This causes Lexa to suffer from creative block, as well as severe headaches, motor failures and even episodes of amnesia.
Sandy realizes the problems that her relationship with Alejandra is generating, so, while Lexa’s life and body are falling apart, the couple will have to decide what’s more important: the love they feel for each other or the well-being of the body in which they inhabit.
