This is Volume 48 - LIONS BEHAVING BADLY of the NATURAL KILLERS - PREDATORS CLOSE-UP Series by IMP Publishers.
Not only is Zimbabwe's Hwange Hational Park home to the world's largest concentration of elephants and wild dogs, but it also supports more than 300 lions, which feast on an unusual abundance of herbivore prey.
Amid such plenty - and with a lack of females to teach them - the male members of one of Hwange's prides have all but lost the skills to kill. and instead eat their prey alive.
Are these lions behaving badly? Or are they just taking advantage of Hwange's living buffet in the most energy-efficient way? Watch the film and decide.
