For the US-release, a lot of plot scenes were removed from Jackie Chan's penultimate acceptable Hong Kong-film, before some disappointing Hollywood-productions. At least, the about 12 minutes shorter version was not additionally screwed up by a new soundtrack, like it happened for example with Rumble in the Bronx or Wheels on Meals. Also, Jackie dubs himself here again.
A Secret Agent loses his memory after falling from a crashing helicopter. He is then chased by several other agency operatives, but he has no idea why.
