Ken Rudolph’s review published on Letterboxd :
This documentary follows Tim Ballard, former lawman, now a leader of a group called Operation Underground Railroad, dedicated to rescuing child victims of sexual predators and bringing to justice the sex traffickers that enslave these children. The film follows this group as it operates stings in Central America and Colombia. For obvious reasons, most of the children and people involved in these operations are fuzzed out or in deep shadow. The film illuminates a serious worldwide problem, and highlights a group of civilians dedicated to the difficult battle against these predators. As a film, however, the diffuse, real-time action footage was often confusingly edited, a function of the fly-on-the-wall and ad hoc nature of the events recorded. Ballard's dedication was inspiring, in any case.
