The Pack (2022)

Rita, a social worker, is conducting an experiment: she organizes an extreme campaign in which she plans to re-educate young offenders. The hike is unexpectedly interrupted by the news of a murder in the group. The teenagers, not believing in a fair trial, decide to run higher into the mountains, taking Rita hostage. Rita's husband goes in search of them, unaware that he has to learn something unexpected about the woman he loves and his marriage.
