Kai finally comes out of his defensive shell and make amends with his daughter Zoie.
Lawrence Cheng is the irritable "Kai", an elderly gent who has just retired from his job and looks forward to a life where he will just be left in peace. It seems that he is not to have his wish though, as he is constantly pestered by a lively brown dog called "Roasted Piggy"! When it polishes off some of his dinner, he takes a water hose to it and is spotted by doggy-do-gooder "Una" (Amy Low) who scolds him for his treatment of the thieving hound. Initially, he's no more interested in her opinion than the dog's, but gradually he begins to warm to the beast as it shows a grim determination to save him from himself. Meantime, "Una" is having a pretty torrid time between trying to save all the strays she finds and dealing with her loved-up colleague (Jay Fung) who wants them to relocate to Edinburgh and get married. Perhaps they can set up a sanctuary there? There's certainly something of the "Greyfriar's Bobby" to "Roasted Piggy". Just to add a little intrigue to this increasingly soapy drama, someone is putting out food for the dogs laced with poison. Can this unlikely pairing unite to save the dogs from this new menace? The amiable Cheng is on good form here as the cantankerous old git who thinks his productive life is done, but the rest of the film rather predictably contrives to introduce the usual elements of familial discord to the plot with his broken marriage, strained relations with his daughter (Fish Liew) and once the grumpiness abates the whole thing becomes just a bit too earnestly familiar. Dog lovers (I"m not) will probably enjoy it more as the story presents them as potent surrogates compensating for lack of human affection in the life of "Kai" and "Una", and there are some moments of both fun and sadness - just not enough of these really help this film stand out from the pack.
