Kev and Rob don their fake antennae and pose as local yokels as they spend twelve months trapped on a primitive planet watching "Fully Dilated". They then explore other times our Starfleet crews have hidden in plain sight, disguised as members of an alien world, including "The Enterprise Incident" (TOS), "In the Flesh" (VOY), "First Contact" (TNG) and "Face of the Enemy" (TNG).
