Valeria (Serena Rossi) is an attractive woman with a strong personality and an unusual profession, born into her deep-rooted disenchantment with love. A true believer in the biological nature of love relationships, she’s a master in the art of seduction and the go-to person for single men looking for romance.
Giulio (Giampaolo Morelli) is a sombre, slightly predictable economics journalist, soon to be married to Giorgia (Diana Del Bufalo). When she leaves him for his boss Alfonso (Massimiliano Gallo), he suddenly finds himself loveless, unemployed and forced to reconsider his once firm mistrust in love strategies. Valeria and Giulio back in his arms but, in the process, one of them will have to change their lifelong beliefs. Is falling in lave a foolproof science or is it a no-rules mystery?
