La llave maestra (S)

Esther, an English teacher who has recently passed the competive exams, accepts the job as a suply teacher in a rural village. The disciplinary system applied by Esther shocks the eight children of different ages that make up her group of class and Pablo, a Physical Education teacher. The eight children are invaded and offended by the new teacher. They will join forces more than ever to get her to leave her job. Esther will learn the value of life by teaching these children and will transform everyone's life. A story of change and search for the true meaning of living. A story to value going slowly and working for dreams without knocking down everything and everyone ahead of you.
