Special ID (2013)

In Special ID (2013), action legend Donnie Yen stars as Chen Zilong, an elite undercover cop embedded deep within one of China’s most dangerous crime syndicates. Living a double life for years, Zilong balances on a knife’s edge—torn between his loyalty to justice and the brutal brotherhood that now questions his every move.
When a ruthless former ally, Sunny (Andy On), rises through the underworld ranks and threatens to expose Zilong’s identity, the mission spirals into chaos. With his cover slipping and a task force closing in, Zilong must fight his way out—one explosive brawl at a time.
Blending high-octane martial arts, gritty drama, and relentless action, Special ID delivers bone-crunching intensity and a powerful story of identity, sacrifice, and honor.
“To take down the triad… he had to become one of them.”
