Bibi and Tina welcome three new holiday guests at Martinshof. They call themselves Disturber, Silence, and Spooky, and they are simply different: Silence doesn't speak, Spooky believes in aliens, and Disturber challenges Bibi to a fight. She is determined to make Bibi stop laughing! Her distrust eventually drives Disturber into the arms of the mysterious V. Arscher, who is planning a cunning heist against Count Falko. The excitement surrounding a meteor shower from space comes in handy for the two, sending all of Falkenstein into a panic. But V. Arscher hasn't counted on Bibi and Tina and their new friends, who won't be fooled.
