Criminal Investigation: You, Me and Him

Solve the case Police number 003199: Echoes on the criminal investigation road Bai Yuyu locked her father Bai Jianming's "003199" alarm number in a box. When her father died at the drug scene, she only thought that this string of numbers was "the murderer who deprived her of companionship." When she graduated from the police academy and was assigned to the criminal investigation team, the old captain handed her the police number: "Your dad always said back then that this number must protect the people." Until one time when investigating a case, she saw an old note left by her father. In the handwriting was the note "the old man lives alone, the doors and windows need to be reinforced"; while guarding the suspect, the aroma of instant noodles wafting in the night breeze suddenly overlapped with the smell of her father coming home late at night in her memory. As her fingertips rubbed against the small scratches left by her father on the police siren, Bai Yuyu finally understood: her father never chose danger, but rather to allow more people to live a stable life. Now "003199" flashes on her uniform, and every case she solves is a response to her father's original intention.
