A knock at the door changes everything. A secret that shatters a family. Consumed by rage, Lydia considers vengeance. But instead, she chooses another path: justice. She calls the police and the hunt begins.

The Hunter is a thrilling true crime documentary following one woman’s relentless pursuit of a criminal which turns into a high-stakes international manhunt. From the Rocky Mountains of Colorado to the streets of Mexico, Lydia stops at nothing - risking her own safety to bring him to justice.

This episode contains very strong language and deals with sexual abuse.
