The Great Yellowstone Heist

The Calhoun family - dad Joseph, mom Kayla, and brothers Cooper and Trey - pull into Yellowstone National Park towing a big camper for a long-awaited family vacation. Trey, who has made his own itinerary and guidebook complete with color-coded tabs, brims over with facts about geysers, safe berries, and how to survive bison attacks, while Joseph declares there will be no devices and no whining, because things always go wrong on vacation and that's what makes it memorable. Kayla, it turns out, has forgotten the milk, the hot dog buns, and the ketchup, which Trey considers a tragedy, since Cinnabons without milk are "downright barbaric."

Soon a friendly couple sets up a tent next door, introducing themselves as Albert, a librarian, and his wife Ivy, an orthodontist. When the neighbors mention a corner store near the campground entrance, Joseph and Kayla drive off to buy the missing groceries while Cooper and Trey stay behind - Trey to unpack and try on his new pocket-covered cargo pants, which he insists "save lives."

Moments later the boys feel the camper jolt and discover the door won't open; the steps have been folded up to block it. The camper begins rolling away behind the neighbors' truck. Albert and Ivy are stealing the camper, and without knowing it, they are stealing the boys too. With their phones left in the car and no way to signal passing drivers - people just wave cheerfully back - the brothers watch helplessly as the thieves haul the camper past Mammoth Hot Springs, move a barricade at a closed re-vegetation area, and hide the camper under thick tree cover. Cooper spots what looks like a gun under Albert's jacket, so instead of fighting, the boys hide - Trey under a dining bench and Cooper in the linen closet.

From their hiding places, the boys overhear the truth. The couple's real names are Matt and Tabitha, and they are bank robbers who have gotten away with two hundred thousand dollars. They are also a bickering married couple who keep pausing their crime spree to practice communication tips from their marriage counselor, reminding each other to say "I feel" and to add "please." Even they admit they aren't cut out for this. Tabitha is delighted to find Cinnabons in the camper - until she discovers there's no milk to go with them.

When the robbers step outside, the boys slip out and run, though Cooper knocks over a broom that clatters into Matt and gives them away. A nighttime chase begins through the dark park. The brothers hide flat under scrub oak while the robbers search, and they realize they've accidentally grabbed the bag containing the stolen money. Trey suggests throwing it to the robbers, but Cooper points out that they've seen the thieves' faces and can identify them, so the couple won't simply let them go. As they flee again, Trey twists his ankle, and Cooper holds him up as they hobble on.

Trey's guidebook knowledge saves them at Mammoth Hot Springs, where he stops Cooper from wading straight across water hot and acidic enough to dissolve fabric, plastic, and even human bodies. The boys take the boardwalk around instead; the robbers, who don't know any better, scald their feet in the springs. Cooper doubts Trey's plan to head for the long-closed visitor center, but Trey remembers something from his itinerary: a 10:30 ranger talk on constellations near the north entrance. When Matt grabs Cooper, Trey shouts "Look away, Cooper!" and blasts the robber with the insect spray stashed in his cargo pants, buying just enough time for the boys to stumble into the middle of the ranger's stargazing presentation. The startled ranger recognizes them as the kids who disappeared with the camper, and when Matt and Tabitha come charging around the corner, the crowd grabs the two fugitives, who promptly blame each other - using their best "I feel" statements.

Reunited with their sons, Joseph and Kayla admit their prayer lives reached a whole new level while the boys were missing, and Cooper says his did too. The parents are proud that Trey drew on everything he learned and that both boys stayed calm and brave, earning praise from the rangers. Trey teases his dad that he did say the more that goes wrong, the more memorable the trip - though everyone agrees the next vacation should be a little less memorable. The only casualty left to mourn is the cookies: Trey ate them all, except for one warm, squashed spare in his cargo pants pocket, which Cooper firmly declines.
