“In a war zone, orders save lives. Love decides which ones.”

 The trailer ignites with rotor wash and sirens as a quake rips through a coastal peacekeeping base. Captain Han Jae‑hyuk (Lee Min‑ho), an elite special‑ops commander, is redeployed to secure a collapsed port while Dr. Kang Mo‑yeon (Song Hye‑kyo) leads a field hospital that’s running on willpower and one generator. Flash cuts: triage in a flooded gym; a sniper glint over broken cranes; a pediatric surgery by headlamp; convoy ambush under sandstorm; mine‑clearing on a ruined causeway; a hostage swap timed to the beat of a failing ventilator. A rogue contractor smuggles biotoxins through aid routes, forcing soldier and surgeon to choose between protocol and the one person who knows the antidote. Banter flickers, promises strain, and a midnight airlift dares the weather and the odds.

Verdict: Big‑hearted, high‑stakes K‑romance—military grit, medical heroism, and chemistry that detonates like a flare.
