Manuela and Rosario are two sisters who, after years of not speaking because of a family secret, find each other unexpectedly in the birthday party of their grandchildren. The kids have met thanks to their nannies, Trini and Milagros, best friends and neighbours. When they discover the conflict that separates the children, the nosy housekeepers will try, clumsily, lovingly and through silly shenanigans, to reconcile the families.
Unfortunately the movie Good Manners is not yet available on HBO Max.
