Don't Go in the Basement!

Marisa and Lorenzo Conchito and their friends want to make an old-fashioned vampire movie. Luckily their friend Jeff knows just the place to film it. His uncle Felix was an actor in several old horror movies, and his creepy old mansion is the perfect location. Felix is happy to let them film their movie at his house. He has just one rule: 'Don't go in the basement!' What secrets could Felix be hiding in the basement? And why does he sleep so much during the day?
