Duty After School (2023)

The students and teachers at Sungjin High School receive a terrifying shock when they witness the start of an alien invasion. Coming from the skies, horrific “eggs” hatch violent insect-like creatures that attack humans. The invasion is worldwide, and the South Korean military fears it will be overwhelmed. In desperation, the President announces that mandatory conscription will begin – and that all third-year high schoolers – male and female – must join the armed forces.
