When a naive girl is captured by a group of people smugglers, she will create a plan to escape from the hell in which she is

Yup, and add specifics for the mental picture, like where this is.

1.
A naive girl planning to escape is a little monotonous. Urgency is good, she 'must escape..' rather than 'planning to'

2.
Getting captured is not the most impressive inciting incident.

Suggestion: She could be someone lured by false promise of a lucrative job or education scholarship.

From your logline, I would probably say your lead is captured by 'human traffickers', not 'people smugglers'.

A coyote is a people smuggler. A coyote helps smuggle people over the border without being caught.
A human trafficker is someone who kidnaps people and then sells them into slavery.
