Basia (Ilona Ostrowska) and Grzegorz (Piotr Adamczyk), a married couple of 25 years, are struggling with routine and fading passion. Their intimate life has become predictable, and conversations about desires and fantasies have long since faded into the background. Determined, Basia decides to take action – she persuades her husband to spend a weekend at an exclusive spa hotel and, armed with the guide "Sex for Dummies," tries to rekindle the old flames of passion. An unexpected encounter with the young and confident Maks (Mikołaj Matczak), Grzegorz's boss, and his spontaneous, sexy partner, Domi (Helena Englert), gives their stay an unexpected twist, rife with tension and temptation. Will this trip help them rediscover themselves and remember the art of being together?
