Mr. CHONG CHI MAN, a Hong Kong film magnate who, after a

long absence, returns to Hong Kong with plans to produce

a new film. His old friends all gather around him, each

hoping to benefit from Mr. CHONG's new project. Mr. CHONG arranges for a group of these friends to visit him

and to spend a few days in his grand old house situated

on one of the isolated island in Hong Kong. This group

of friends each carries different objectives on this trip.

The visitors' voyage to the island is marked by the rescue

of a young man nicknamed 'Little Sprin' who claims to be

an illegal immigrant from China. He accompanies the

others to the island. Upon their arrival, the visitors

are treated to a banquet presided over by their host, Mr.

CHONG, After dinner, MR SOO gives a demonstration of

his Kung Fu prowess hoping to impress Mr. CHONG, only to

be met with mockery. Angered and shamed he gets into a

fight with MON LI TAN. MON, in the ensuing chaos, makes

the first of many attempts to kill Mr. CHONG. Strange

and sad music is often heard in the house. The source

of which is soon discovered to be Mr. CHONG's daughter,

CHONG HUE TUNG, playing the piano.

Not suspecting that 'Little Sprin' is actually a thief. Mr.

CHONG allows him to stay behind to serve as caretaker of the

old house. Meanwhile, detective PAO suspects that MON LI

TAN has tried to kill Mr. CHONG and warns him of the situation.

On the other hand, PAK FU YUNG, HA LUM UM and TAI MA S00 tries

every way to fulfill their objective. However, this leads to

confusion and a series of hilarious situations. The old

house continues to have a lot of mysterious happenings

culminating in the disappearance of Mr. CHONG.

The disappearance of Mr. CHONG leads 'Little Sprin' to

suspect several of the visitors of having done away with Mr.

CHONG after failing to obtain favors from him. However,

detective PAO suspects there may be more behind the story.

CHONG's daughter, HUE TUNG, recounts that she had been

knocked unconscious while talking to her father the night

before he disappears. 'Little Sprin' who was eavesdropping

under the bed is also rendered unconscious. Regaining

consciousness, they discover Mr. CHONG's disappearance. A

tape recording of Mr. CHONG's voice is accidentally found

by PAK FU YUNG under her pillow. He asks her to endeavor

to find him. KIU KAM FA learns of the tape recording and

insists in participating in the search. The visitors all

discover that one door in each of their room leads to the

basement which they proceed to search. However, no trace of

Mr. CHONG is found……

The strange sound and the mysterious happenings continues

to occur in the house. The group finally decides to

investigate into this matter and Mr. CHONG's son, TING

SIN, is elected to lead and direct the operation. Mean-

while, MON LI TAN discovers that TING SIN is actually a

schizophrenics. He informs everybody but nobody believes.

The group even assist TING SIN in locking MON in the basement.

KIU KAM FA, hypnotized by CHONG's lawyer - YEUNG, leads

the group to believe that she is possessed by CHONG's

spirit. Everybody is fooled with the exception of

Detective PAO who plans to investigate. In the mean-

time, CHONG's son, TING SIN, has turned schizophrenic and

altered personalities. He traps a member of the group

in the basement and proceeds to torture them. However,

MON arrives, in the nick of time, to save the victims but

is not quick enough to defuse a bomb planted by TING SIN.

The explosion causes much damage to the room but luckily

nobody is hurt. In the meantime, PAK FU YUNG disappears

and MON, fearing that TING SIN might harm her, locks TING

SIN in the basement. The film siren, LAM LAM, discovers a

boat anchored near the island, everybody packs to leave

only to discover that the boat malfunctions……

TING SIN, under guard in the basement, manages to overcome

his guard and escape. Mr. CHONG , who is alive, is actually

living in a cottage where he has brought SIU SIU under the

mistaken impression that she is his love, PAK FU YUNG, At

this stage, SIU SIU has no choice but to Mr. CHONG, she is

only disguising as her mother, PAK FU YUNG. In the meantime,

several of the man attempt to repair the boat, leaving KAM FA

and PAK FU YUNG ashore. The two are soon captured by TING

SIN but manage to escape. PAK FU YUNG and KAM FA then go

to Mr. CHONG's room to search for SIU SIU, However, PAK FU

YUNG suddenly disappears and SIU SIU reappears.

Together at last, Mr. CHONG and PAK FU YUNG prepare to leave

the island but are caught by 'Little Sprin' and his two

uncles. The three held him for $10,000,000 ransom. Mr.

CHONG informs them that the key to the safe is in the possession of his lawyer, YEUNG. 'Little Sprin' attempts

to trick lawyer YEUNG into giving him the key but arouses

the lawyer's suspicious and calls for help. Detective PAO

and MON answer YEUNG's call of distress, overpower 'Little

Sprin' and lock him in the basement. The safe is opened

by lawyer YEUNG in everybody's presence. The sight of the

contents overwhelm KAM FA and TAI MA S00 with greed.

Lawyer YEUNG hears notices coming from Mr. CHONG's room at

night and proceeds to investigate, opening the safe to

check its contents. However, TING SIN suddenly appears

and overcomes her. Meanwhile, KAM FA sneaks into Mr.

CHONG's room to find the safe wide opened, she then proceeds

to take the money out. HA LAM LAM and SIU SIU discover KAM

FA's absence and fearing her safety, they begin to search

for her and find her in front of the safe. UM FA asks that

they allow her to take some of the money from the safe, and

in pity, they let her. The remaining money in the safe was

shared amongst the other members of the group. In the

meantime, 'Little Sprin's' two uncles are looking for him

but are discover by Mr. CHONG's housekeeper, LUCY and locks

them in the basement.
