The cheetah had its claws in the teenager's back, its killer teeth poised near his neck as it pinned the boy to the ground.
And then, a swift movement, a flash of bright orange, and it was all over.
The boy was saved, the cheetah being held to the floor nearby and frantic guards at the South African lodge converging.
The orange flash was the teenager's dad Dave Driver in his bright Pacific-inspired shirt, throwing himself at the wild animal in a desperate bid to save his son Isaac's life.
Driver spoke to the Herald this morning from South Africa where he is on holiday with Isaac, 14, wife Mandy and their daughter Eve.
"All of a sudden there was this commotion... it was quite strange," he said.
"The cheetah just went for Isaac, I saw him biting Isaac and I'm thinking, 'He's not biting his head.
"I grabbed its neck and pulled it off him and threw it to the ground and pinned it until the guards came.
"I just remember seeing its face near Isaac's... its head on his shoulder... and thinking if it turned around and bit him... I remember saying, 'It's not getting his head'.
Driver said the cheetah was "actually quite big" and he could see it had huge teeth and claws.
"It was just instinct really, I just grabbed it and pinned it to the floor," he said.
"I remember looking at it on the ground and thinking that it wasn't as strong as I thought it would be.
"Then I thought that I didn't know what was going to happen next... as soon as it was on the floor I suddenly realised, 'This could go quite bad'.
"Luckily it didn't go mental, if it had started thrashing around and going for me..."
Driver said Isaac was pretty impressed with his heroic dad.
He said he was as wrong as the lodge was to put his son in that position.
Driver said he put his son in an enclosure with a wild animal and that's the consequence.
The family will stay in South Africa until Wednesday and are off to see lions and rhinos tomorrow.
The attack has far from put them off - the day after the attack they were out on an elephant safari.
"South Africa is an amazing place," said Driver.
Massey University lecturer in animal behaviour and welfare Rachael Stratton told the Herald yesterday that cheetahs weren't usually aggressive but because they were wild animals could be unpredictable and there was a myriad of reasons why the animal may have attacked.
