Dempsey and Makepeace are shadowing Frank Egan, who has just got off Scott free on a murder charge. His next big job seems to involve 'a bird man' and 'haggis'. It leads to Makepeace posing as a floozy and Dempsey as a pilot.

Frank Price is sprung out of jail, only to be killed by his accomplices. Spikings suspects Price's boss Jack Lang, but when Lang's granddaughter Debbie is kidnapped it seems like someone else is trying to instigate a gang war. Meanwhile, Dempsey is more interested in wooing fellow American Angie Hughes.
