In 1945, in the Train Station of Bogota, Colombia, a dead girl is found in a trunk. The case is assigned to Detective Mariano Corzo (Edgardo Román), and he has to deal with the yellow journalist Hipólito Mosquera (Diego Vélez) meanwhile he solves the mystery case, besides nobody knows who the girl is, or who put she in the trunk either. The things turn worst when Mosquera says in a newspaper that the trunk is pink, when it is actually brown and wooden. With the help of the bar tender Martina Quijano (Dolores de Heredia), Corzo will find an answer for the question: ¿Who killed the girl and why?
