Two twelve years old girls, Amber Zhou and Brenda Wang, decided to hang-out in the hotel where their fathers are busy with preparations for a major auction event. Their fathers provided a hotel room for the two of them, together with Amber's older brother. The two girls decided to roam around and explore the hotel. They suddenly bumped into a stranger in the hallway who seemed anxious. The man suddenly told them that they should leave the hotel because there are dangerous people inside that might cause a commotion before the man ran away. Amber and Brenda stared at each other confusedly. They were about to leave when they saw a gold bowtie on the floor. Brenda thought that it might belong to the stranger. The two got suspicious when Brenda remembered the uniforms of the staff working for the auction night and thought about what the man said. They went to the function room where the auction event will be held and saw hotel workers wearing bow ties of the same color. Amber and Brenda suddenly thought that someone might sabotage the event. Will they be able to catch the culprits before it gets too late?
