orologio en Altadefinizione. Maria Ada is a famous urban legend that tells the story of a teacher who died leaving two sons behind while his ghost occasionally comes to life trying to recover them. Oscar and Jose, two friends and former classmates, tell about the tragic ghost apparitions and their constant bickering with an albino boy. A friend from the same classroom could only see the ghost, because in Equatorial Guinea they say that albinos have four eyes.
