Meet the Deedles 1998

Fraternal twin brothers Phil Deedle Paul Walker and Stew Deedle Steve Van Wormer lead a sunlit, carefree life in Hawaii, living off the wealth their father Elton Deedle Eric Braeden has earned. On their eighteenth birthday, after a lazy surf session, they’re expelled for truancy, and their father decides to shake them out of their comfort zone by enrolling them in a survival boot camp in Yellowstone National Park. The plan is simple in theory, but it’s quickly complicated by the involvement of the former owner, Major Flower M.C. Gainey, who intends to run his own version of training, much to the boys’ horror. What begins as a game of mischief and ignorance soon spirals into a real test of grit and ingenuity.

En route to the camp, a reckless turn of events sees Major Flower drive them off a cliff, and, convinced he has killed them, he vanishes into the forest. The brothers, resourceful as ever, steal clothing from a nearby campsite and descend toward a ranger station by luge, hoping to find safety and guidance. A comic yet telling mix-up occurs when rangers misread the twins’ clothes labels and mistake them for two famed naturalist recruits named Mel Ana Gasteyer and Mo Megan Cavanagh. The confusion sets the stage for a clash between two worlds: the glib, sun-warmed life of island leisure and the disciplined, rule-bound world of park service work.

Waking up in a Yellowstone hospital, the Deedles seize the chance to reinvent themselves as Mel and Mo, plunging into the routine of foraging and field duties with a mix of luck and improvisation. This uneasy ruse becomes more complicated when the real Mel and Mo finally arrive and expose the imposters, a revelation that upsets Jesse Ryan [A. J. Langer], the park’s capable lieutenant who has taken a shine to Phil, and stirs conflict with Captain Pine [John Ashton], the station’s stern commanding ranger. The twins’ deception earns them swift consequences, including expulsion from the park, yet their stubborn streak pushes them to keep meddling in park affairs and protect Yellowstone from a darker scheme.

The real danger, however, comes from Frank Slater [Dennis Hopper], a disgruntled former park ranger who hatches a plan to divert the hydrologic flow of Old Faithful through a network of underground pipes into his own land, hoping to birth a rival, privately controlled geyser—what he envisions as a new, profitable park. He intends to execute this during the park’s anniversary celebration, humiliating Pine in the process. Even after their expulsion, the Deedles press on, determined to thwart Slater’s audacious scheme.

A daring infiltration follows: the twins parachute onto Slater’s property, are captured, and—thrillingly—are aided by a friendly prairie dog they had befriended earlier. Donning heat-resistant suits, they manage to halt the diversion of superheated water to Slater’s “New Faithful,” while Old Faithful erupts in response to the stoppage. The resulting geologic reaction explodes across Slater’s land, creating a natural wave pool that soon becomes a magnet for visitors. Slater and his henchmen are arrested, and the park’s leadership recalibrates around the Deedles’ accidental bravery.

Back at the ranger station, Elton arrives to express pride in his sons’ persistence, and the brothers—now reinstated into the Park Service—find themselves drawn closer to Jesse. The trio decide to cap off their unlikely victory with a surf session atop the new wave pool, turning Yellowstone’s iconic landscape into a dynamic, family-friendly attraction where old rules are rewritten by a pair of risk-taking twins and their steadfast ally.
