Enterprise is about to research a new system when another ship warns them about a storm they are too slow to evade. The crew’s only chance turns out to be seeking protection in the warp nacelles, on a narrow catwalk. They discover they are no longer alone aboard – aliens of the same race who warned them are about to take over the ship. On questioning their „friends“, they admit to being deserteurs who fled their corrupt commanders. Archer and his crew now have to get rid of their unwanted guests while they can only move about their own vessel in radiation shielding suits.
