"The only dream I ever have is the surface of the Sun. Every time I shut my eyes, it's all I ever see."[My review will not spoil the end of this movie for you; minimal spoilage.]
It is the year 2057. The Sun is growing colder, and life on Earth is in danger of extinction. Eight astronauts on the ship Icarus 2 are on a mission to re-ignite the Sun. Things go wrong, as things in movies always do, and difficult decisions must be made.
