1) Six students are trapped inside their collapsed school after a violent earthquake strikes during classes. They must work together to overcome obstacles like aftershocks and sealed exits to escape.
2) Along the escape route, one student is killed by falling rubble after disobeying instructions. Another gets trapped under rubble and insists on moving it herself, but her attempts are unsuccessful and the group has to leave her behind.
3) The remaining students are eventually rescued, and Jake admits his feelings to Emma, who reciprocates them. More survivors are found than originally thought, showing the disaster was widespread.
