Lucia and Maria, both in their forties, are best friends despite having personalities which are complete opposites. While Lucia is very rational and pragmatic and has given up on men after her divorce, Maria is spontaneous and naïve -- and quite addicted to men, hooking up with a new one almost every night. But one night, the perfect man falls into Maria’s bed! He’s charming, sensitive, passionate and mature! The problem is he’s just 19 years old, and because of a misunderstanding he falls in love with Lucia.
