在这部城市猎人剧场版：海滩之战动作/动画/喜剧片中,美树与阿香好不轻易有机会参加海滩城市饭店的开幕仪式，没想到海怪和阿獠不但爽约，还意外为一个女孩子引起一场火拼。原来流亡海外的哥斯迪罗共和国的前独裁者基利阿姆将军为报复美国想利用海滩城市饭店的电脑入侵美国的战略防卫系统......
Rival private eyes Ryo Saeba and Umibozu must find a way into a high-tech luxury hotel to rescue their friends who are being held hostage and stop a mad South American dictator's plans to use the hotel's supercomputer to unleash a nuclear holocaust. Highly reminiscent of Die Hard, right down to a scene where Ryu bunjee-jumps off of the roof of the hotel skyscraper with a fire hose.
