Mean and Lean Cows (Flacas Vacas) is an ironic comedy of an unhealthy friendship. Olga, Teresa and Magdalena have been friends since they were born. For years they vacationed together. A few years ago, Teresa got married, and for some years they didn’t see each other as much. A casual meeting is the catalyst for a weekend together even though it becomes obvious that everything they share is in the past. The weekend turns out to be a bigger disaster than expected. At the end they are no longer best friends.
