To steal a mafia's fingerprint password, elite agent Tyler disguises himself as a clumsy genius slacker and deliberately gets close to Ava, the mafia heiress and school beauty—proud and tsundere. Through a series of deliberately staged "accidental" encounters and ambiguous flirtation, the conflicted Ava finds herself both disgusted and intrigued. Suddenly, mercenaries attack the campus, and a deadly biochemical leak turns the entire school into a zombie-infested zone. The two are forced to team up to survive. On the run, they protect each other and watch each other's backs, caught in a constant push-and-pull of raw chemistry. When mutated mercenaries corner them, they both drop their disguises at the same time: the gentle nerd is actually a ruthless intelligence agent, and the pure school beauty is an undercover female cop.
