The Monster Squad is a society of young pre-teens who idolize classic monsters and monster movies and hold their meetings in a tree clubhouse. Club leader Sean (Andre Gower), whose five-year-old sister Phoebe (Ashley Bank) desperately wants to join the club, is given the diary of legendary monster hunter Dr. Abraham Van Helsing (Jack Gwillim), but his excitement abates when he finds it is written in German. Sean, his best friend Patrick (Robby Kiger), and the rest of the Monster Squad visit an elderly man, known as the "Scary German Guy" (Leonardo Cimino), actually a kind gentleman, to translate the diary. When the Monster Squad wonders how the German man is so knowledgeable about Van Helsing's battle with monsters, he wryly comments that "he has some experience with monsters" and his shirt sleeve briefly reveals a Concentration camp number tattoo.
