Martina, a young woman of roughly thirty, decides to take her life. She loves her husband Marc, but also loves Lara, a woman she met at the riding stable where she keeps her horse. Unable to reach a decision, Martina prefers to do away with herself, given that the loss of either one would be too painful for her to handle. Marc knows nothing about the relationship with Lara. He has only three days to discover the secret life of the person he has been living with for years and save her.
