Falling Skies Season 3 episode 9: Journey to Xilbalba
5 second plot: The Volm bunker (where the weapon to save mankind is held) explodes. The human bunker (where they live) collapses. And the rest of the episode they try to get out. And they catch the mole.
5 second review: Ridiculous, filled with crazy coincidences and boring as shit. I've just about had it with this crap.
