The Icaris II is Earth's last hope at survival. Their mission is to deliver a nuclear blast to the dying sun, thus saving mankind. Eight years prior, the Icaris I disappeared on the same mission, so the crew is single minded in their intent to complete their task.
As the story plays out, there is suddenly a distress beacon, which turns out to be from the first ship. At this, the crew divides on whether to change course to intercept the ship, or continue towards the sun. While some argue that they should not deviate course as failure means the Earth dies, others state that the other ship will give them two chances to jump start the sun - which makes me question why in the eight years since the previous ship disappeared why they didn't come up with a better plan.
From this point on, the crew is divided and problem after problem confronts them. The slow pacing runs through more than half the movie before a new subplot changes the whole tone of the film, and annoyed me as it seems the obvious solution was overlooked. When all was said and done, I found myself unsure as to what to think of this film.
