Two Vietnam Veterans have realistic nightmares about the war. So real are these nightmares that they start getting injured in them, and bringing things back that they had in the dream.
They then buy weapons and go in to try and get one of their friends out that originally died in a POW camp during the Vietnam war. This is made harder by a traitor from the US Military Corps.
这是比佛利山超级警探的第二集。艾索（艾迪墨菲 Eddie Murphy 饰）在上一集破案后老老实实地回到了底特律当他的刑警，回到底特律的他顿时感到百无聊赖。于是，艾索每周都会找他在洛山矶办案时结识的好朋友兼好搭档洛山矶警局的局长博格密尔（罗尼考克斯 Ronny Cox 饰）出海钓鱼。
可是这周博格密尔临时取消了和艾索的钓鱼活动，事后艾索才得知原来博格密尔卷入了一单复杂危险的案件侦察中。博格密尔不幸在调查中被犯罪枪击受伤，现在正住在医院里。向来讲义气、嫉恶如仇的艾索又怎能按耐得住，于是他马上来到了洛山矶约上最佳搭档比利（祖德莱茵霍尔德 Judge Reinhold 饰），要一展身手为好友报仇。
