6All over the world, frog populations are declining, with many frog species headed toward extinction. Cousins Stowe and Wheaton join on a mission to capture and breed endangered frogs on this third mission for ResQ, their organization to save endangered animals. A jaguar, a band of migrants, darkness, and flooding confront them in the indigenous village they make their base. Wheaton's engineering skills and Stowe's skills as a naturalist both come in handy as they seek to save not just frogs this time, but also villagers.
