"Law's Tea House" is out-of-date. Shopkeeper Dragon and chef Tiger are already late fifties old men who have waited for their paralyzed kung-fu master Law Sun to wake up for 30 years. Property company messenger Cheung is ineffective in work, aimless in life. Cheung used to be a kung-fu enthusiast but had been forced to give up due to suffering from asthma. Cheung's passion in kung-fu revives after Tiger fights off the bully gang for him and he also encounters adorable lass Kwai. Cheung gets involved in the dispute of the young proprietor Mang's retrieval of properties including "Law's Tea House" during which Cheung accidentally triggers Law Sun to wake up. Law Sun's return brings back vigor for "Law's Tea House" to resume "Law's Martial Club". He trains Dragon, Tiger and Cheung severely to fight for their lost dignity.
