Lidia is a responsible and dedicated maid for a hugely wealthy, elderly Tijuana matron who loves only her pet whippet. Rafael is a quiet and dignified janitor who buys a new pair of shoes to celebrate his imminent retirement from the large corporate facility where he's worked for 30 years. When Lidia's boss dies, leaving everything to her dog, and Rafael's plans get derailed, they both turn to criminal subterfuge to get what their harsh lot in life has denied them.

In the run-up to a song festival, all kinds of intrigues and pressures are unleashed behind the scenes: the script must be continually adapted depending on who momentarily prevails in the backroom maneuvers, with record companies, politicians and schemers of various calibers intent on fighting each other without holds barred to grab victory in advance. In the meantime, the organization is falling apart. Having recruited the almost complete Bagaglino cast, under the parody of Sanremo we see yet another rehash of "Champagne" or "Bucce di banana".
