An undercover cop befriends a yakuza underling who through his contacts helps him infiltrate two rival Yakuza gangs. He pits the two rival gangs against each other in hopes that they will cross each other out.
A lightning-paced 60's crime film from Japan's Nikkatsu Studios, 3 SECONDS TO EXPLOSION packs enough subterfuge and action into its 84 volatile minutes to fill out a dozen pictures made anywhere else.
A once-powerful yakuza clan disbands as a result of a police crackdown but one small group refuses to bow to police pressure, and launches a campaign to take over Tokyo's drug, prostitution, and gambling rackets.
One of Chiba's most enjoyable films.
