Lockdown

A merciless battle breaks out in a laboratory guarded by the army... Under a hail of bullets, the attackers manage to flee with a sample of an ultra-secret biological weapon! Meanwhile, it's the beginning of an ordinary day for the students of class 1A at Kaishin High School... until the group of fleeing thieves arrives at the school! They barricade themselves inside, taking teachers and students hostage. Who are these heavily armed terrorists? What cause are they fighting for? Mystery... Their leader, a young woman named Hozuki, arrives seriously injured at the infirmary. It is her right-hand man, a masked soldier, who takes over the operations. His message is clear: opposing his orders means death! But the terrorists are players and, rather than shooting the rebels, they prefer to manipulate their victims to turn them against each other and thus better enslave them... The situation gets out of control when Hozuki decides to use the stolen biological weapon: the virus spreads, with no hope of treatment! Even for trained soldiers, the situation is out of control...
