DOLPHIN

Anguished and frightened, Diana believes that the lady she saw dead in a toilet booth from a highway's resting area was the same person who was run over by a truck 20 minutes later, because both had a ring with a strange symbol (a dolphin inside a pentagon). The policemen were very skeptical about her story, so she begins to investigate on her own; she does this with the help of David, who didn't happen to be on the highway by chance. In the end, David tells her the truth: he was involved in the blackmail scheme, along with the two women and the criminal, but not on commiting the murders.

Angustiada y asustada , Diana cree que la mujer a quien vio muerta en la cabina de un retrete de la autopista es la misma que fue atropellada por un camion 20 minutos despues, porque las dos tenian un anillo  delfin pentagonal. Los policias fueron escepticos de su versión [version of the facts],  asi que ella empezo una investigacion por su cuenta, con la ayuda de David, que no estaba casualmente en esa autopista. Al final, David le dice la verdad: estuvo implicado en la operacion de chantaje, junto con las dos mujeres y el criminal, pero no en cometer los asesinatos.
