Mom’s Got a Date with a Vampire

13-year-old Adam Hansen (Matthew O'Leary) and his best friend Duffy (Jake Epstein) have tickets for a concert, and his 16-year-old sister Chelsea (Laura Vandervoort) has a date with her dreamy boyfriend Peter. Because Adam hasn't done his homework, instead making up a story using an article from the magazine The Weekly Secret, and because Chelsea calls Adam a dweeb, their mother Lynette (Caroline Rhea) grounds them both. Chelsea and Adam will do whatever it takes to get their mother out of the house, so they set her up on a date with a mysterious man named Dimitri (Charles Shaughnessy). Everything seems to go according to plan, until their 8-year-old little brother Taylor (Myles Jeffrey) sees Dimitri turn into a bat, and realizes that he's a vampire.

His brother and sister do not believe Taylor, so he calls Malachi Van Helsing (Robert Carradine), the vampire hunter. The night that their mother goes out with Dimitri, Taylor follows them. Not wanting their mother to come home and extend their punishments, Chelsea and Adam follow Taylor. Adam realizes Taylor's hunch about Dimitri was right when he looks in the mirror and notices Dimitri does not have a reflection. Along with Chelsea, he sets out to stop Dimitri, who puts their mother in a trance and plans to take her to his mansion. Meanwhile, Malachi Van Helsing arrives and begins to hunt down Dimitri, only to discover that he was being followed by Taylor.
