Mercy (2016) Spoiler-Free Summary – What It's About

In a bustling urban hospital, a former military doctor has traded battlefield triage for the quieter rhythm of a nursing shift, yet the calm is only a veneer. When a ruthless Irish‑mafia syndicate force‑fully claims the facility, the sterile corridors become a tense arena where ordinary medicine collides with organized crime. The stakes rise dramatically when the mob captures her young son, turning the hospital into a pressure cooker of fear and resolve.
