The series is directed by Sir David Attenborough, and will show the footage collected from cameras, which have followed 5 species of endangered animals, for years.

It will show the power dynamics and complex relationships between tigers, lions, hunting dogs, emperor penguins and chimpanzees. 

Describing the series, BBC said:

(It is) An intense portrayal of the lives of these animals as they unfold, day-by-day, hour-by-hour, where the tiniest incident may end up having a huge consequence on their future. Their chances of success depend on their own strength of character, their choices and on luck. But these animals do not operate alone – their success or failure will also hinge on how they work with, or against, their own families.

The series, which has been shot over 4 effing years, will be presented by Attenborough itself.
