Aunt Bing, around 65 years old, had a strained relationship with her son after losing her husband at an early age. Feeling empty and lonely, she fell into the arms of an online scammer, who lured her into investing her life savings in a fraudulent stock trading platform. Unfortunately, she lost everything she had invested. Hong Kong Securities and Futures commission's investigation team, led by senior manager Tony Tam, along with new team member Crystal Yu, embarked on an investigation to uncover the individuals responsible for the fraudulent platform. They traced the suspected mastermind, a Hong Kong citizen named Tang Chi-Kwun, who was residing in Malaysia. With the assistance of local authorities, Hong Kong Securities and Futures commission conducted a video interview with Tang. However, he came prepared, making numerous excuses such as feeling unwell, having a poor memory, and displaying unstable emotions to evade questioning. Despite feeling helpless in the face of his despicable actions, Crystal, with her compassionate stance, could do little to confront him. On the other hand, Tony, experienced and unfazed by such tactics, approached him from a different angle and eventually saw through Tang's scheming. With relentless pressure, Tang was forced to confess to his crimes. Although they succeeded in preventing another scam from taking place, the insidious greed led Aunt Bing to fall into an even larger stock market fraud once again...
