HI‑FIVE — Official Trailer
Starring: Yoo Ah‑in, Park Jin‑young, Oh Jung‑se.
“We don’t save the world—we high‑five it back together.”

A blackout surgery links five strangers through a single donor and a glitch of fate: when their palms meet, impossible powers sync and surge. Yoo Ah‑in’s streetwise EMT keeps the misfits alive long enough to learn the rules; Park Jin‑young’s rookie engineer codes a “handshake protocol” to steer the chaos; Oh Jung‑se is the velvet‑smiled fixer buying organs—and superpowers—by the piece.

Trailer pops: time stutter on a subway brawl, a Han River bus tilt reset by a perfectly timed five‑tap, grocery‑aisle shards hanging midair, and a rooftop chase where every slap trades abilities like cards. The crew must pull one audacious heist: steal back their donor’s heart from a vault that feeds a black‑market miracle.

Verdict: Zippy, big‑hearted, and neon‑slick—K‑action comedy with inventive powers, punchy edits, and found‑family feels.
