The Stars At Night

Buenamigo proposes that all California-class ships be replaced with his Texas-class ships and Freeman challenges him to a race. Mariner becomes suspicious of where Aberdeen is getting her money, but learns that she is funded by Picard and confesses that she was just looking for a reason to return to Starfleet. Freeman claims victory because while the Cerritos lost the race, it was so her crew could double check there were no lifeforms on a desolate planet which the automated ships did not do. Rutherford realizes that the automated ships use Red's experimental code and it was Buenamigo who erased his memories. Buenamigo orders the Texas-class ships to destroy the Cerritos, but the corrupted systems kill him and fire on all of Starfleet instead. Seeing this in a news report, Mariner and Aberdeen arrive with the other California-class ships and together they defeat the Texas-class ships.
