Ti Lung plays a Vietnam vet who's now an 'honourable' mercenary-for-hire taking on an assignment tracking down an assassin who's fled to Cambodia after murdering an industrialist from Hong Kong. He recruits a team for the task which consists of who's who of the Shaw Brother's action stars (Lo Lieh, Johnny Wang Lung Wei, Wong Yue, Chan Wei Man and comedy relief Nat Chan). However once they arrived for the mission nothing is what it seems with the standard plot-twists and turns as we find out who's the traitor among the group.

'Ghostly Mother Blue Flower' Chiu Choi-wan has abducted a group of virgin boys and girls for the nourishment of her mind and soul. Alarmed by the abduction, Yiu But-fan, Kau Suet-mui and Hung Tin-bo make a night raid on the Hanshan Temple to release the children and set a torch to the bandit lair. Fuming over the arson, Chiu casts a spell on Kau, who kills the father of Chuk Yuk-heung in her cross-dressing persona as Yiu. Confronted by the angry Chuk clansmen at the Chuk Fortress, Yiu tries futilely to defend his innocence. Believing that Chiu has masterminded the framed murder, the fugitive infiltrates the White-bone Yinyang Cave where he finds himself attacked by Kau and Chiu. Demon-vanquishing Magic Monk, Chuk and Hung helped Yiu wrestle Chiu, who fled. Kau is nursed back to health by the monk and joins the fellowship in their quest to annihilate the demon. With all her venomous needles forfeited to the monk, Chiu gets her comeuppance, slain by Chuk's flying dagger.

Having pledged his alliance to the anguished son, Taoist Tranquil of Emei vows to eradicate the menace at Mid-Autumn Festival when his junior disciple Kau Suet-mui is challenged to a duel with Chiu. Kau's fellow disciples Hung Tin-bo and Chuk Yuk-heung follow the orders of their master to roam the martial world and tumble into a bandit lair. Extricated from danger by the Taoist, the duo join hands with the passer-by Yiu to thwart Lai's assault on Kau by sorcery, again aided by the Taoist. Yiu, Kau and her peers head back to the Kau Fortress where a martial contest is being held to select a prospective groom for the daughter. Kau overwhelms Lai in the ring but concedes defeat to Chiu.
