Quemar las naves (2007)

Eugenia is a former pop singer who is bedridden and dying of cancer. Her 19-year-old daughter Helena dreams of traveling the world and learns foreign languages at home and wishes she could be a glamorous pop star like her mother was. Helena cares for her mother with help from their housemaid Cahya, who also keeps the aging house in working order. Sebastian is Helena's teenage brother who attends a Catholic high school run by a Monsignor who plays classical music over the loudspeakers, thinking it will calm down the boisterous kids. Sebastian's dreams are simple: he merely wants to move to the beach. Helena is smart and pretty but she has no friends, male or female, and is totally devoted to her mother's care--and is on the verge of initiating an incestuous relationship with Sebastian. Sebastian however, is falling in love with a boy at school named Juan who is the school roughneck and the son of a single father who owns a little bar.
