A test pilot accidentally becomes microscopic and ends up inside the body of a timid grocery clerk.
The story
In San Francisco, aviator Lt. Tuck Pendleton volunteers for a secret miniaturization experiment and is shrunk to microscopic size. During the process, a rival organization attacks the lab, and the wounded experiment supervisor injects Tuck and his pod into an unsuspecting passerby, Safeway grocery clerk Jack Putter. Unaware of the situation, Tuck must navigate the human body to establish contact with Jack. The duo must then collaborate to help Tuck escape the host body and prevent the rival organization from seizing the stolen miniaturization technology.
Full plot (contains spoilers)
After being injected into Jack Putter, Tuck realizes he is inside a human and establishes communication. They learn that a rival group led by Victor Scrimshaw stole a vital computer chip, with the second chip remaining in Tuck's pod. Jack and Tuck's girlfriend, Lydia Maxwell, pose as a henchman to steal the chip from Scrimshaw, but they are captured. During their imprisonment, a kiss transfers Tuck into Lydia's body. The criminals then shrink a henchman and inject him into Jack to find Tuck. Jack and Lydia eventually shrink the criminals and Scrimshaw to half-size while trying to retrieve the chip. Tuck discovers he is inside Lydia, who is pregnant. After another kiss transfers him back to Jack, they attempt to enlarge him. During the process, a henchman attacks Tuck in Jack's esophagus, but Tuck kills him in the stomach acid. Finally, Jack makes himself sneeze to eject the pod from his lungs, enlarging Tuck. Tuck is reunited with Lydia, and the film ends with a wedding where Jack serves as the best man.
