Danny Trevanion, his family and companions face life-changing challenges in this gripping sixth series of Wild at Heart. Danny's wife Alice is pregnant and sensitive to her surroundings. So when a lion attack endangers her, she becomes traumatised and in danger of shutting down all together. With Danny appointed State Vet, he can't be in two places at once and is frequently away from Leopard's Den grappling with problems of his own. Olivia's friend Thabo has been released from prison and comes to stay, but this leads to an intimacy which not all approve of - and a risk of much more when his brother comes calling. But Leopard's Den faces its greatest crisis ever when a mining concern initiated by Christian Peeters starts blowing holes and digging up the landscape. His plans involve the gradual take-over of Mara from Vanessa, and driving a road through the Trevanion family home. Anders is prepared to fight dirty, but once the gloves are off, everyone is endangered - animals and humans alike.
