Mottomo Abunai Deka (1989)

Taka and Yuji stumble onto a fresh lead in a fifteen-year-old investigation, but with the clock ticking down to a four-day deadline before the statute of limitations runs out, they race to link the old case to a shadowy network of illegal arms dealers. Every hour counts as they close in on the gunmakers, hoping to crack the case before time—and justice—slips away for good.
