Minas, a conscientious and honest employee, is responsible for procurement at the company where he works. His wife, Eva, is a faithful and obedient spouse who embraces her husband's principles, but she enjoys luxury, furs, and jewelry. One day, her husband's boss approaches her and suggests that she recommend one of his suppliers to Minas, without any compensation. Thus begins a story in which, behind her husband's back, Eva earns money, which she justifies as an inheritance from an uncle. However, when Minas discovers her trick, every trickster sits on his bench.
