Tanner and Frankie are the new investigative journalists for Our Incredible World. In this series on woodland caribou, their assignment is to learn as much as they can about why this species is at risk, and what is being done to make sure it doesn't become extinct. Each episode provides a new adventure and new insights. Deep in the boreal forest Frankie and Tanner meet with research scientists, and assist with field research. From an Aboriginal elder they learn about Cree lifestyle, and how Aboriginal traditional knowledge is helping protect the caribou. Finally, the team experiences the high tech world of CSI where caribou genetics is the mystery to be solved in the "crime lab." Throughout their adventures, Frankie and Tanner make a great investigative team.
