The thatcher household is burglarized. Suspicions center on an Africa-American welder named Marquis ( another aquaintance of Paige's, he taught her how to weld.) Drew and Libby debate over whether having a gun is the best thing to do. Corky and Arnold are alone watching (what else, a cop show) when Corky hears sounds from outside. He gets the gun, goes outside in that sneaky cop fashion (emulating the show) and fires. Turns out Marquis was returning something, and the family realizes how much they overreacted. (thetvdb.com)
