An old flame discovers her ex-boyfriend from the past is a relocated FBI informant out to stop the bad guys.
 
The chemistry between Mel & Goldie is just plain FUN, which in turn makes the entire movie entertaining.  
 
FUN FACT:  Goldie Hawn did most of her own stunts, after being convinced by Mel Gibson to do so. She was originally reluctant to perform them, fearing the harsh and overwhelming nature of the tasks. She was eventually so pleased with her stunt performances that she kept her stuntman's jacket after filming resumed, and as of 2017 still exhibits it next to her Oscar statuette.
