According to Blastr, the movie focuses on the adventures of a young William Adama during the 10th year of the first Cylon war. Snippets based on an earlier press release, here's what we have to look forward to:
"Ensign William Adama, barely in his 20's and a recent Academy graduate, finds himself assigned to the newest battlestar in the Colonial fleet ... the Galactica. The talented but hot-headed risk-taker soon finds himself leading a dangerous top secret mission that, if successful, will turn the tide of the decade long war in favor of the desperate fleet."Will update more when I have more info.
