Dora Martinez (Angela Boj) wins a lottery prize and decides to give it away to all her friends and family. A documentary filmmaker (Javier Coloma) hears about her and decides to do a story about it: interview everyone who knows her and then he follows up her life. As research is on, he realizes that she is indeed a generous character. However, the director does not believe just so much goodness and thinks that after her exemplary behavior lies hidden motivations.
