Spy Games (1990)

When a Japanese rock band decides to give their lead singer Takako a birthday she'll never forget. One of the members get's one of his friends (who also works in an acting troupe) to pretend they are bad guys that want to kill her and her father (who they say is a spy and he's also hiding in Hong Kong). But the joke goes too far and Takako actually heads off to Hong Kong to try and save her Father from these thugs. But things start to look like they could actually be coming true for her.
