Carry on hotel (1988)

Mr. Lau is a seedy detective who sets up cameras to record an illicit affair. Things go awry however when a hideously glam rock band checks into Lau’s room, and gets a free show via his hook-up. Meanwhile, silly thief Donald Ng uses ninjitsu to fool the locals while a womanizing tour guide gets stalked by not one, but two pretty women. And Buddy Cheung is a lowly mechanic at the hotel who lusts after gorgeous executive Sunflower. But his tomboy co-worker Boy George secretly pines for him.
