The Loud family is going to be spending the day at a national park called Grand Venture State Park. To pass the time on the drive, Lucy suggests that they play with her fortune-telling cards. She predicts that Lori will go on a long trip (Lori thinks that fortune means she'll go to Italy with Bobby), the universe will open doors for Lola, Luan will soon be blown away, and Lisa will make a scientific discovery before entering the park, although Lisa doesn't believe it. When Lucy gets to Lincoln, however, she's too horrified to reveal his fortune. Desperate on what his fortune is, Lucy tells Lincoln that his day will end in "tragedy". Almost immediately, Lincoln is petrified.
When the family takes a break at a gas station, all except Lincoln exit the van. Lincoln says that he fears of stepping out due to Lucy's prediction. Suddenly, Lori slips on some oil, and crashes onto a pile of garbage. As Lori contemplates on how embarrassing that was, Lucy stated that Lori would go on a "long trip", thus making her prediction true (much to Lori's disappointment). As Dad fills the tires with air, he accidentally "blows away" Luan with the air hose. As the Loud kids enter the store, a man named Mr. Universe leaves the door open for Lola. These two turn of events prove that Lucy's predictions are real. Inside the store, Lynn struggles to hold her pee in, Leni falls in love with a pair of hiking boots, Lana finds a dollar in the toilet, and Luna gets two bags for the price of one from a vending machine. These events only lead Lincoln to become more scared, but Lisa tells him that all these events are just pure coincidence. Lincoln realizes that Lisa's fortune hasn't happened yet, and theorizes that if her fortune doesn't come true, his fortune won't happen.
The family arrives to Grand Venture State Park, and Lincoln tries to hurry his sisters into going into the park so Lisa doesn't make a scientific discovery. Before Lisa can enter the park, a giant egg falls in front of her and it immediately hatches. What Lisa finds inside is an owl with deer antlers. This happens to be Lisa's "scientific discovery", causing Lincoln to become more panic-stricken, believing that his fortune is bound to come true. Lisa then proceeds to show the park ranger her newest discovery.
Throughout the day, the family enjoys the visit at the park, and partake in fun activities like exploring a cavern, swimming in the lake, enjoying the breathtaking scenery, fishing, and having a picnic. Throughout all these activities, Lincoln refuses to partake in any of them, giving over-exaggerated and over-the-top reasons as to what might happen to him.
Later on in the day, Lisa has set up a press conference to show off the owl with antlers (which she labeled as "the Dowl"). As the family and several news stations watch Lisa show off her latest discovery, the antlers on the owl suddenly fall off. Lisa examines the antlers and notices that the antlers say "Made in China". Suspicious, Lisa demands the Park Ranger to spill the beans. The park ranger admits that it was all a hoax. He did this because nobody has come to the park in years ever since the signature geyser stopped erupting, and thought a little publicity would bring people back. When Lisa tells everybody that the "Dowl" was nothing but a scam, Lincoln realizes that Lucy's fortune for Lisa hasn't come true, and all his worrying made him miss out on all the fun. Lincoln believes that his day really did end in tragedy, though Lisa still doesn't believe it.
As the family is about leave, Lincoln, saddened that he didn't have any fun during the visit, tells the viewers that the lesson he learned was that you should never live your life in fear, or else you'll miss out on all of it, and that would be a tragedy. Suddenly, Lincoln feels the ground vibrate, and hears a loud boom in the distance. He looks through a bush, and notices that it's the signature geyser erupting for the first time in years, and he's the only one to witness it. Lincoln tries to tell his sisters about his amazing discovery, but they're all too tired to listen. Despite this, Lincoln proclaims that he did have the best day ever.
Lisa, still in a state in disbelief, asks Lucy if she's going to toss her cards away, since her and Lincoln's fortunes never came true. Lucy says that there is only one card left, and uses it to prove that her fortunes are true. She pulls out the card, and says that "the end is near". When Lisa tries to disapprove of this, a "The End" card pops up, making Lucy's fortune come true.
