No Deposit, No Return

A 1976 live-action Disney film.

Tracy and Jay 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 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 and Bert, two down-on-their-luck safe crackers with a huge sum of money to pay to their loan shark Big Joe.

Meanwhile, police sergeant Max Turner has spent his career chasing down the infamously unlucky safe crackers, but his search has been fruitless. Partnered with rookie detective Longnecker, 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:
 * Construction Zone Calamity: Bert chases Jay who chases Duster into a construction zone.
 * Corruption by a Minor
 * Faux Affably Evil: Gangster Big Joe at first appears like a cheerful and polite man, but when discovering the kids' identities he drops it.
 * Humiliation Conga: Turner's and Longnecker's car.
 * Latex Perfection:
 * Locked In A Safe: The children during the climax.
 * Parental Obliviousness
 * Pity the Kidnapper: Sums up J. W. Osborne's attitude quite well, much to the frustration of Turner.
 * Scooby-Dooby Doors
 * Smelly Skunk: Duster. He never actually sprays anyone, though, he just scares everyone away.
