The Defiant is surveying a rare subspace compression phenomenon in Federation space, with the aid of the runabout Rubicon, which is miniaturized (along with Dax, O'Brien, and Bashir), when they are attacked by Jem'Hadar who board the Defiant and capture its officers. The tiny Rubicon manages to get inside the Defiant, where the officers are working to retake the ship as they are made to repair the warp drive. Can the Rubicon's crew somehow aid them...and can they ever return to normal size?
