Dolphin / Shark
The film centers around a writer, Alan Tam (Anthony Wong), who has spent the last decade in a mental hospital. Upon leaving, he rents an apartment in an abandoned building which contains a clock that sends him back to 1984. The only person that can hear Alan during this time is one of the previous tenants, a young girl named Dolphin (Dolphin Chan). A strange romance soon develops between the two, and so when her sister Whale (Perrie Lai) begins dating a suspicious professor (Lawrence Ng), Alan helps Dolphin to find out the shocking truth about her sister's beau.
Five cops work and get on each other's nerves during a hot summer. Tak is a gambler, too much so for his girlfriend to risk marriage. Daddy, a single father, is harsh with his son who reminds him of the woman who abandoned them. Monk is mercurial, talkative, a show-off. Kong, a steady family man, keeps the peace. Sam is new, hoping to fit in and make it as a cop. Three brutal and murderous robbers are on the loose, and so is a former soldier, embittered over the loss of his pension, using very real bombs to extort what's due him. It's a dangerous job, and the cops must watch each other's back, regardless of their personal problems.
