David is happily surprised after a game of truth or dare at Maria's slumber party lands him a date with one of the school cheerleaders. Determined to keep David out of her social circle, Maria schemes to break up the new couple but fails miserably, prompting her to try something she has never done before - ask Uncle Ernesto for advice.

David's decision to run for president of his class turns Joaquin into a crazy campaign manager. Meanwhile, Ernesto and Daniel team up to find Ernesto a new girlfriend.

Ernesto invests in an old Airstream trailer and hires a tough but charming biker babe, Rosa, to be his "maintenance woman," secretly hoping he can turn her attention away from the trailer and re-focus it on him. Meanwhile, when David and Sarah decide they are ready to have sex, they have an embarrassing encounter with Joaquin and Elizabeth.
