Woody Allen took a Japanese spy movie called
Kagi No Kagi, and replaced its original dialogue with an entirely new plot. In its revised state, this film follows the adventures of agent Phil Moskowitz who is on a deadly mission to secure the recipe for the "world's greatest egg salad." However, Moskowitz, with the help of the beautiful Suki and Terri Yaki, must prevent this unique recipe from falling into the hands of the evil Shepherd Wong. The group Lovin' Spoonful recorded the majority of the songs for this film. ~ Iotis Erlewine, All Movie Guide
