Dora Explorer Márquez is a precocious girl who loves the jungle. Madelyn Miranda plays young Dora. She and her professor parents, Cole (Michael Peña) and Elena (Eva Longoria) are explorers. They encourage her inquisitiveness and enthusiasm. When Dora is six, her older cousin Diego (Malachi Barton) moves to the city with his parents which saddens Dora.
Dora’s parents have been trying to find Parapata, The Lost City of Gold. Once the parents find enough clues to locate the mysterious city, they emphasize that they are not treasure hunters. They are only in pursuit of knowledge to find the city. Despite Dora’s protests, her parents do not bring her with them in their search. They send her (now older and played by Isabela Moner) to the big city to live with her high school age cousin Diego (now played by Jeff Wahlberg).
At the high school, Dora’s unlimited positivity is scorned by stereotypical high school students. She knows more than the other students. She especially annoys the stuffy Sammy (played by Madeleine Madden). On her first day, Dora also meets the awkward Randy (played by Nicholas Coombe).
On a school field trip to the natural history museum, those four teenagers reluctantly form a team for the class treasure hunt at the museum. A staff member lets the team into a restricted basement to see ancient Egyptian relics. That was not the best move because treasure hunters who are on the trail of Parapata kidnap the four. They hope the kids will find Dora’s parents and unwittingly help them find their bounty.
In Raiders of the Lost Ark-style, they must escape dangerous traps beforeo they find the treasure. Randy names these challenges “Jungle Puzzles” that he is familiar with from computer games. The obstacles require the four to develop bonds of friendship and trust to succeed in the quest.
The film is filled with lots of lighthearted humor. Even the villains are more humorous and bumbling than scary. Dora’s pet monkey Boots adds more humor to the film with his playful resourcefulness. The film has its moments of suspense but Dora and her friends handle them with grace.
Dora is a really enthusiastic and positive person. The hidden gold is the attraction for villains while Dora, her friends and parents do not want the wealth. After returning from their adventure, Dora and her companions have a new freedom. Their negative classmates can’t reduce their enthusiasm. Dora has the opportunity to do more exploration with her parents. However, Dora decides to leave the rain forest so that she may study the “indigenous people” of her new high school.
