A domestic comedy of marital temptation and jealousy, following a married couple whose relationship is tested by outside flirtations — with a guardian-angel figure literally watching over the husband's conscience, per the poster's own imagery. Directed by Raphael J. Sevilla and starring Emilio Tuero and Charito Granados, adapted from a French farce by playwright Louis Verneuil (whose marriage comedies were popular sources for Mexican cinema of the era). I couldn't confirm a detailed scene-by-scene synopsis, so treat this as a general outline based on the genre and source material.
