Beneath the fake blood and cheap masks of countless haunted house attractions across the country, there are whispers of truly terrifying alternatives. Looking to find an authentic, blood-curdling good fright for Halloween, five friends set off on a road trip in an RV to track down these underground Haunts. Just when their search seems to reach a dead end, strange and disturbing things start happening and it becomes clear that the Haunt has come to them...

Following immediately after the events of THE RAID, Rama (Iko Uwais) is forced to reinvent himself as an undercover cop in order to provide protection for his wife and child. Working for the anti-corruption taskforce led by the one person he can trust, Bunawar, he is given a mission to engage himself as an enforcer for a local mob boss, Bangun. Finding a way in through Bangun's son Uco, Rama must hunt for information linking Bangun with police force corruption. All the while, he harbors a dangerous and personal vendetta for revenge and justice that threatens to consume him, and bring both this mission and the organized crime syndicates crashing down.
