On his third day under the instruction of the head chef Ms. Li, a sum of money disappears from the school office. The teachers at the school turn their suspicion to Lu Bin. While Ms. Li is a strict teacher to Lu Bin, she also sympathizes with him. If Lu Bin is identified as a thief, he will be expelled from the school. Two teachers decide to investigate further, and Ms. Li is forced to face her suspicion of Lu Bin, along with another unexpected secret.
