These Last Seconds

A shipwreck, 3 survivors marooned on Mars. A time-traveler, a love-obssesed guy, and a dying girl. The time traveler had just saved Earth by steering the ship onto Mars, but only the love-obsessed guy has a cooling system installed into his suit. They have 2 hours to get off the planet before the biggest threat to mankind reachs them. Will they survive? Will they save Earth again? Will things evr be back to the way things were?
