Once a playboy, Alexander Drako is now the happy father of three and eager to celebrate Valentine's Day with a special party held on Friday night to accommodate his nocturnal vampire friends. Everything is ready except for a small detail. Alexander has forgotten to buy the roses and orchids for his beloved Ravenna. Unable to disappoint her, and accompanied by his loyal friends, Marcus and Samuel, he sets out for Wolf's Haven, a rehab center for paranormals, hoping to find some flowers left for sale in their greenhouse.
After a honeymoon around the world that lasted half a year, Peter and Ophelia have just landed back in Rome. While he would like to relax in their apartment, Ophelia is eager to see her friends. Most of all, she can't wait to hug Quintilius, her adoptive father.

Ophelia's call reaches Quintilius at Wolf's Haven, where he's volunteering, and he rejoices at finally seeing her again. However, he isn't thrilled to see Peter, the man who stole the heart of his little princess. A sudden crisis at the rehab center forces Quintilius to focus his thoughts and energies on looking for Luisa, a girl who's run away with a dangerous gang member.

By fate's design, all the friends have reunited at Wolf's Haven and agreed to help Quintilius in his quest. Will they be able to save the girl and return to their loved ones in time to celebrate Valentine's Day?
