Synopsis:

Agatha receives a visit from Florence, an old woman who wants to get in touch with her dead husband, in order to prove to her son that the man’s ghost really exists and for this reason they must not sell their house. Initially terrified about meeting the ghost, Agatha later decides to help the old woman with the collaboration of her daughter Milla and an unwilling Ulysses who right up to the end will not believe in the existence of the ghost. Ulysses becomes completely involved not just because the Institute he runs is asked to certify to the absence of ghosts in the old woman’s house, but also because an accident at Agatha’s house forces her and Milla to move in to Ulysses’s house with all their belongings.
During their investigation, the duo discover that Florence’s husband was really killed by the housekeeper, in order to steal a winning lottery ticket from the man. Now that Florence and her son are in possession of the winning ticket that is worth millions, there is no further need to sell the house.
But another, much more important investigation begins. Ulysses is determined to help Milla discover the identity of her father whom the girl has never met.
