Liz Dunn is a student at an exclusive private school who is head over heels for Mike Steel, a handsome classmate whose father is a well-known American rock star. Liz, however, is self-conscious about her looks and is convinced Mike would rather be with the prettier girls in her class. Liz is also unenthusiastic about an upcoming field trip, in which she and the other students will have to camp out for three days while studying local geography. Liz confesses her infatuation with Mike to Martin Taylor, a science-minded geek and longtime friend who happens to be in love with Liz, though she prefers to ignore it. Martin proposes a solution to both of Liz's problems; he's found an underground bunker built during World War II near the school grounds, and he arranges a little party in which Liz and Mike will spend the three days of the field trip in the bunker, with class couple Geoff and Frankie going along, giving Liz a perfect chance to impress Mike with her charm. The students lay in a supply of food, water, and booze to last them for three days, but after 72 hours, they discover they've been locked in, and they're not sure if Martin intends to let them out.
