Lin Yang, a college entrance exam failure worrying about retaking the test, catches his homeroom teacher Zhou Ming handing an encrypted USB drive to a foreigner! To his shock, a "National Security Mission System" pops up on his phone—unlocking IQ buffs and clue-reading abilities for counter-espionage tasks. Torn between Zhou (who helped him with math last week) and the military coordinates in the USB drive, Lin Yang reports him, only to face retaliation: security stops him, the cafeteria aunt spills soup on him, even his crush tells him to "mind his own business"! Using the system's "super brain," Lin Yang cracks the Morse code in Zhou's lesson plans, tracks down the spy den. Finally, he learns Zhou was his father's comrade, and his father's "car accident" was a spy murder? Watch how this failed examinee turns from a "college loser" to a "national security prodigy," outsmarting spies with the system and his wits, and avenging his father!
