There is a scene where the Stephanie Chao "a good vampire" bites a willing person that wants to be temporarily turned to save his girlfriend and then has sex with him.

First she is seen disrobing to a slightly sheer top, no nudity but glimpses of the side of her breasts and her nipples through the garment. Then she bites and kisses his neck at the same time repeatedly. Next scene seconds later Stephanie Chao is having sex on the man nude. Breasts and nipples are briefly shown several times as she is riding him while he is turning into a vampire. he is bare chested. no other nudity is shown.

The nudity is fairly brief as most of the "sex scene" is actually the guy having flashbacks to the events over the prior few days.

Some martial arts fighting.

When the vampires bite people in the neck blood pours down.

Vampires fight, a bit of blood.

A monk/vampire kills a vampire by chopping it's head off.

A few fist fights.

A few scenes have a vampire being exposed to sunlight and bursting into flames.

This is a low budget movie, so all of the "gore", blood, and killing has a budget look to it. Not too realistic.

There is a motorcycle chase with a few crashes. Nothing too bloody or gory, most of the crashes look fairly staged.

A few swear words.

Some casual drinking and smoking.

Vampires could be scary for some.

The motorbike chase scene is quite intense.
