A scene-by-scene remake of the Mexican caper movie La hermana Trinquete about a professional thief who is an expert in changing her appearance to outwit the police.
When she is nearly caught by the police the thief (Lucero) hides out in a luxury hotel in Acapulco, adopting a number of disguises – including that of a black chambermaid – to rob fellow guests. When the police inspector in charge of the investigation is about to catch her she takes refuge in a convent, where the Mother Superior discovers that her skills are very useful.
The inspector is hot on her trail but she escapes again and is soon back to her tricks.
Estele Sanchez was the makeup artist.
