The third and final part in the infamous Hong Kong Triad/spy trilogy. I liked this one the best, and upon watching it again I still think it's the best of the three. It's just not quite as slick and cunning as I remembered it to be. It's a rare example of a third film beating out its predecessors though.
The story is both a sequel and prequel to the first film. Part of the film sees how Ming picks up his job again, suspecting another promising superintendent to be a mole for the Triads, while the other half harks back to the past, following Yan on his first undercover mission.
Leung and Lau are both splendid, the film ties together some remaining strands in interesting ways and the switch between both timelines is interesting. The presentation is a tad basic though, with too strong of a focus on the narrative. A fun film and a worthy finale, but not impressive enough to be a personal favorite.
