Synopsis

Walter hat ein schlechtes Gewissen, weil er Paige verschwiegen hat, dass er mit Flo zu einem Vortrag gegangen ist. Sylvester, Cabe, Paige und Ralph bemerken auf dem Rückflug von Hawaii nach L.A. einen weiblichen Marshall an Bord. Die Frau registriert Funksignale aus dem Frachtwerkschacht und kann eine Bombe als möglichen Auslöser dafür nicht ausschließen. Ralph hat derweil andere Sorgen: Patty scheint nicht an ihm interessiert zu sein.
