Culebra, an island off Puerto Rico, is used by the USA as a target area for bombing practice with live ammunition. The documentary depicts the struggles of the people of Culebra as they take increasingly militant action to put a stop to the target practice bombing of the area.

In 1998, David Sanes, a security guard of the US Navy base in Vieques, died from a projectile from a military practice. As a consequence of that incident, the people of Vieques and Puerto Rico joined in civil disobedience in the restricted area of the Marina so that no more bombs could be dropped.
