In a quiet coastal village, life seems to flow without major upheavals, until a strange event turns everything upside down. A group of explorers and tourists arrives in the area to enjoy a day of sun and beach, but soon discovers that an old and dangerous chemical experiment has unleashed a colony of giant ants that seek to expand their territory. These creatures, much more intelligent than they appear, begin to attack the unsuspecting visitors, turning their day of fun into a desperate fight for survival.
