Colombian terrorist Luis Cali (Andrew Divoff) takes an American prep school hostage as a means of gaining his drug lord father's freedom. Privileged yet rebellious students Joey (Wil Wheaton), Billy (Sean Astin), Snuffy (Keith Coogan) and Hank (T.E. Russell) find that they are better equipped to deal with the threat than the mostly ineffectual government agencies sent to rescue them. With resourceful Billy as their leader, the students struggle to defeat the terrorists and save the school.
