The only connection to the first movie is that it also stars Conan Lee (though not playing the same character) and is a crime/action film set in HK. It's not a bad film by any means though it is a bit disjointed.
There is a plot (of sorts) involving an error prone HK cop (Danny Lee) and his lazy American born nephew (Conan) who is visiting him, plus a prostitute (Ellan Chan) and a stolen ring. Don't let the plot worry you too much though, it is often fairly incidental in these kinds of films.
The first half of the film has that strange though enjoyable HK movie mixture of comedy and ultraviolence and the usual goofy characters.
In the second half though the action ups a gear and the final action showpiece is pretty spectacular (martial arts on a bus, i loved that obviously). Tiger on the Beat 2 is enjoyable if uneven film and not that original, it probably would have been better to have given it a stand alone title but lets not worry too much about that.
