Bear Grylls takes Oscar-winning actress Kate Winslet on the ride of her life as they "paramotor" to the top of the Snowdonia Mountains in Wales. They will descend through jagged, rocky cliffs and ascend up deep canyons to get to their destination on the coast. They will gather trout and earth worms and must set up camp in the very windy environment to rest before their final swim in the icy ocean waves. Along the way, Kate talks humorously about her humble upbringing and also reveals the unwavering determination that has helped her achieve movie star status.
