故事发生在清末民初之际,世道离乱,人鬼同途。被称为鬼城的丰都,传说每当夜幕降临便有酷似故宫的鬼城和鬼哭神嚎的奈何桥。客死他乡的孤魂野鬼只有在法术高强的茅山道士的引领下,才能起尸蹦蹦跳跳回到故里安葬。某个月黑风高的夜晚,破落户陶宇和胖子怀恨盗挖土匪军阀胡大帅家的坟墓,结果偶然撞见一伙赶尸队伍。天降死鬼,吓跑了两个家伙,他们好不容易得手的珠宝也被赶尸队伍抢走。原来这支队伍假借赶尸之名,实则帮助盘踞一方胡大帅的走私鸦片烟土。
两人知晓了胡大帅的秘密,在日后一连串的冲突事件中,他们将和这个恶棍展开连番较量……。While rowing out in the ocean, Mitch rescues an underwater photographer, named Linda, floating on some wreckage. Linda's somewhat disjointed, frantic story about something attacking her in an underwater cave which killed her partner and destroyed her boat is misconstructed by Kay Morgan, an ambitious, publicity seeking newspaper reporter, who creates a media frenzy by starting rumors about a "creature in the bay." Harvey Miller, the new lifeguard and prankster, benefits from the events by selling undersea creature T-shirts. Meanwhile, Shauni rescues a young girl from drowning and soon becomes compelled to rescue the girl, her brother and their mother from the life they live in the slums of South-Central L.A., much to Eddie's chagrin. While Shauni deals with her possessive father who disapproves of her lifeguard job, Mitch also pressures Captain Thorp to ask for funding for new advanced motorboats, called Scarabs, for the team.。
