A 1976 live-action Disney film.

Tracy (Kim Richards) and Jay (Brad Savage) are two children who are excitedly looking forward to an Easter vacation with their mother. Unfortunately, their mother is too busy to see her children, and they are instead being sent to their wealthy grandfather J.W. Osborne (Creator/DavidNiven) for the umpteenth time. Tired of the same vacation they get every Easter, Tracy and Jay run away from the airport (with their pet skunk) and end up getting taken in by Duke (Darren [=McGavin=]) and Bert (Creator/DonKnotts), two down-on-their-luck safe crackers with a huge sum of money to pay to their loan shark Big Joe (Vic Tayback).

Meanwhile, police sergeant Max Turner (Herschel Bernardi) has spent his career chasing down the infamously unlucky safe crackers, but his search has been fruitless. Partnered with rookie detective Longnecker (Charles Martin Smith), he is put on the case of the apparent kidnapping of the two children for a $100,000 ransom. This is, of course, just a brilliant scheme by the two children to help their two benefactors out of their debts.

However, not only does the grandfather fail to take the ransom seriously, but Big Joe finds out about the ransom, and decides to kidnap the children for real. Meanwhile, the kids' mother comes to Los Angeles to help Turner and Longnecker bring Duke and Bert to justice...

!!Examples of tropes include:

* ChaseScene: One of the most climactic scenes in the film.
* ConstructionZoneCalamity: Bert chases Jay who chases Duster into a construction zone.
* CorruptionByAMinor
* HumiliationConga: Turner's and Longnecker's car.
* InstantConvertible: Done to a police cruiser at one point.
* KnightOfCerebus: Big Joe is set up to be this...[[spoiler: then gets outsmarted by the kids]].
* LatexPerfection: [[spoiler: Turner tries to disguise himself as the grandfather. [[RealityEnsues An unusually realistic version]], as the mask fails to [[ExpressiveMask show expression]], and Turner complains about how hot and stuffy it is to wear it.]]
* [[LockedInAFreezer Locked In A Safe]]: The children during the climax.
* MamaBear: Karen flies all the way from Hong Kong to San Francisco when word get to her that [[spoiler: the kids are missing]]. She also [[spoiler: jumps in to Bert and Duke's car as it's driving away]], which is a pretty gutsy move.
* ParentalObliviousness
* PityTheKidnapper: Sums up J. W. Osborne's attitude quite well, much to the frustration of Turner.
* ScoobyDoobyDoors
* SmellySkunk: Duster. He never actually sprays anyone, though, he just scares everyone away.
* SympatheticInspectorAntagonist: Sergeant Turner. Subverted with Longnecker, thanks to him being annoying.
