From the official website:
"U.S.S Enterprise crew members meet Hal Jordan and the entire Green Lantern Corps Green in an adventure that spans space, time and all the colors of the spectrum. Set inStar Trek's 23rd Century, the balance of the universe will be tested when the Green Lantern Corps' Power Rings come into the possession of certain Star Trek characters while a dark and powerful evil looms around every corner. Only the combined power of the Green Lantern Corp and the Federation stand any chance of stopping those who worship evil's might."
