As the last remnants of sunlight fade from the desolate landscape, humanity teeters on the brink of extinction. Fifty years have passed since the initial attempt to reignite the dying star, and the consequences of failure are dire. The once blue skies have given way to an eternal darkness, plunging the planet into a deep freeze. It's 2057, seven years after the catastrophic mission went awry. A new team, led by astronaut Robert Capa (Cillian Murphy), is assembled to correct the mistakes of the past. Joining him on the perilous journey are two other astronauts, Corazon Carya (Michelle Yeoh) and Harvey Perkins (Chris Evans). The crew of the Icarus spaceship embarks on a treacherous 93-million-mile journey to the Sun, carrying a state-of-the-art device capable of reigniting the star. However, as they approach the blazing inferno, the team faces unexpected challenges and internal conflicts. Their mission is further complicated by the presence of Pinbacker (Mark Strong), a ruthless and cunning scientist who will stop at nothing to achieve his own goals. As tensions rise and the stakes grow higher, the Icarus crew must confront their own mortality and the very survival of humanity. With time running out, the team discovers that the Sun's dying process is accelerating at an alarming rate. The ship's instruments begin to malfunction, and the crew realizes they may not be able to complete their mission as planned. As the fate of Earth hangs precariously in the balance, the Icarus crew must find a way to overcome their differences and work together to succeed where others have failed. Will they be able to revive the Sun and restore life-giving warmth to a desperate humanity, or will their efforts ultimately prove futile? In this gripping sci-fi thriller, the very future of our planet hangs in the balance.
