When Martin meets Paola during a business trip to Chile, he is charmed by her sensibility and simplicity. But living in different countries, everything points out that they will never see each other again; however, a series of magical events will make them fall in love and plan a future together. Love leads them to accept the challenge of transforming an old and abandoned lighthouse that overlooks the Pacific Ocean into their dream house; and without planning it, they meet an old man that will change their lives forever: the guardian of the light. A wonderful love story that encourages us to trust the power of love: capable to overcome prejudices, distance, and all the impossible odds that can only be overcome by crossing the crystal walls that life and society places in our hearts and in our minds.
