Echo 3 is an action-drama series that follows the disappearance of scientist Amber Chesborough near the Colombia–Venezuela border. When she goes missing during a research mission, her husband and her brother—both highly trained U.S. special forces soldiers—launch a dangerous search for her, uncovering a complex web of political conflict, guerilla warfare, and hidden secrets.

Cameo FX contributed visual effects work to the series, delivering digital compositing and visual enhancements that supported the show’s intense action sequences and cinematic storytelling.
