In San Pedro Sula, the capital of Honduras' Cortés province, the rate of kidnappings and deaths due to dust begins to increase. This trade, which now even goes beyond the provincial borders, causes panic in the country. Moreover, people who were found to be doing this trade were found dead in strange ways when they were caught. An unknown person nicknamed C, who is identified as the leader of the trade, sends a letter to the police. The letter contains only the name and home address of one police officer. In addition, C will reveal who he/she is, but asks him/her to find the clues he/she gave first, and thus the cat and mouse game begins between C and our police officers.
