Among the Living (2014)

A woman shuns away kids asking for trick or treat on Halloween while her husband is watching a TV channel showing an interview of a soldier who speaks about the genetic mutation, adverse effects, radiation n other war effects and immediately the wife goes berserk. Fast forward and we are introduced to three adolescents who bunk their school on the last day before summer vacation to avoid detention. The kids wander about and land up in an isolated n abandoned studio on the outskirts of the town and they witness a woman being held captive by a masked man.
