Forever Unfaithfully Yours (2018)

Josef and Miluška have shared a lifetime together—she teaches aerobics and tends to her husband and teenage daughter with endless devotion. Josef genuinely loves her, but he can’t resist the pull of younger, prettier women. Their marriage, like his failing publishing house, is falling apart. Enter Aunt Marta, a seasoned marriage counselor with a radical solution. Her prescription? Cheating. She insists they must catch each other red-handed to save both their union and Josef’s business.
