In the near future, scientists have discovered dangerous abnormalities without our sun. The gas giant has become increasingly unstable and has begun expelling deadly solar flares bound for earth. As mankind is helpless to stop the coming solar event, people across the world scramble to make peace during earth’s last moments. Sundown is about one man’s quest to make peace with his own past before time runs out. Through coming to the aid of a family in need, Theo Hannah races against the apocalypse to redeem the sins of his past.

 

After being released from prison after a five-year sentence, Theo begins a journey to redemption at Earth’s most desperate hour. Shortly into his travels, Theo comes across the Martin family who are greatly in need of a savior. Rebecca Martin has been seriously injured in a horrific accident and it is now up to Theo to help the family reach safety in a nearby shelter.

 

During Theo’s travels with the Martin family, it is revealed that he has just been released from prison. Upon learning this news, Kyle Martin insists that Theo immediately leave the family alone. However, the rapidly escalating solar event causes Theo to jump into action and come to the aid of the Martin family once more.

 

Theo sees the Martins to safety and continues on his own personal journey. Just as the solar event is reaching its height, Theo comes to his destination. Finally at his place of peace, Theo can spend his last moments at the grave of his wife and daughter.
