The Patels - Rohan, Anu, Gina and their cousin, Nimal - live on a wildlife conservation in North India. Travelling home by train for the summer holidays, the children not only acquire a new addition to their family - Hunter, the dog - but also meet Peter, a young detective, who grew up on the Patiyak Wildlife Conservation with them. Peter has been assigned to their Conservation to deal with the problem of peacocks being killed for their feathers - peacock feathers can be sold at exorbitant prices! Angry and upset, the youngsters assure Peter they will assist him, to the best of their ability, in saving the birds. While making plans to save the peacocks, the Patels decide to form a group called the Junior Environmentalists and Conservationists (the "JEACs"), and invite young people who want to protect animals and save the planet from further destruction to join up. Upon reaching home, the JEACs set off on their investigation to discover the crooks and bring them to justice.
