The Battlestar Galactica and the rest of the fleet are running perilously low on food with the only route to more through a highly radioactive nebula.  It's up to the raptor pilots to safely guide the rest of the fleet through.  Meanwhile an old friend of Kat's shows up on the Galactica threatening to reveal her past if he doesn't get what he wants.  Starbuck finds out and threatens her but she tells her that she wants to tell Adama the truth, after the operation is finished.
