"Ageless"

Following a complete re-fit of the ship, select members of the Phoenix’s crew conducted diplomatic talks at a conference. Upon beaming back the team were faced by a transporter accident and all members of the away-team found themselves being de-aged back to when they were children. It fell to the rest of the crew to tame the young versions of normally perfectly respectable crew and work out how to undo the transporter accident to restore them back to usual.
