So Weird (1999)

The show starts with Fiona Phillips, the daughter of two singers, who's been mourning her father's death for most of her life. She's also obsessed with all things strange, from ghosts to aliens to trolls, investigating them all on her laptop while traveling cross-country on her mother's tour bus. Although her brother and friends rarely believe her, Fi refuses to give up. As her search for the mysterious goes deeper, she learns things about herself, and more importantly, her father. After a few years, she passes on her quest to her friend, promising young singer Annie.
