A young girl secretly adopts a runaway monkey only to have to deal with the simian's mischief-making tendencies in this family comedy. Young Eva (Thora Birch)'s dreams of having a pet are frustrated by the objections of her mother (Mimi Rogers) and allergic stepfather (Christopher McDonald).
When she finds a stray capuchin monkey, she cannot resist it, and she keeps the animal -- which she names Dodger -- hidden in her room. Eva doesn't know that Dodger has just escaped from an evil organ grinder named Azro (Harvey Keitel, playing a regrettable Gypsy stereotype), who had trained the monkey to become an accomplished pickpocket.
Old habits prove hard to break, and Dodger begins stealing everything in sight, landing Eva in plenty of trouble. Her problems are only compounded by the actions of the unscrupulous Azro, who wants to find Dodger and use him as part of an important robbery.
The standard misunderstandings and slapstick comedy ensue, with the spunky Eva struggling to protect her new pet and herself. While probably too predictable to appeal to many adults, Monkey Trouble's skillful animal antics and resourceful young heroine may prove entertaining to youngsters.
