Greetings from Tucson

After David and Sarah accidentally get drunk at a party, David calls Uncle Ernesto instead of Joaquin to pick them up. Realizing Joaquin will be furious with them for their deceit, David and Ernesto scheme to re-enact the evening by planning a fake party.

David finds himself in hot water after he promises to drive Sarah and her friends to a concert before he actually gets his driver's permit. Determined to make the concert, David bites the bullet and asks Joaquin for driving lessons, landing him in the driver's seas for the ride of his life.

When Joaquin gets David a grueling job as a caddy in the hot Arizona sun, David goes behind his father's back and gets a cushy job as a lifeguard, but his secret is revealed when he saves a woman's life. Meanwhile, Ernesto is hurt when his son Daniel seems to prefer hanging out with Joaquin.

After David complains about not being popular like Maria, Ernesto advises him to join the high school football team and ride the bench to avoid the bone-crushing plays, but when Joaquin realizes his son is not in the game, he talks the coach into sending him in to play which ends in a surprising accident. Meanwhile, Maria applies to college and writes an essay about her mixed heritage that makes fun of a certain part of her mother's body.

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.

When Elizabeth takes a job as a bank teller to earn extra money needed for Maria's college education, Joaquin predicts that the kids will suffer, then proceeds to make sure that they do. Meanwhile, Ernesto tries to avoid getting a promotion.

Elizabeth and Ernesto take on extra shifts at work after Joaquin's factory workers go on strike leaving him at home with David and Maria, and a lot of time to fill. To make matters worse, David realizes he has feelings for Sarah and the only person around to give him advice is his dad.

While Elizabeth and Maria scheme to teach Sarah's narrow-minded mom a lesson, David plots revenge when his dad first gives him permission to spend the holidays skiing with Sarah, then goes back on his word. Meanwhile, Ernesto allows his friends' band (Los Lobos) to practice in the garage, but is horrified when Joaquin wants to join the band as their lead singer.

Maria advises David on how to get Sarah to kiss him, but things get really hot after Joaquin catches them in the act. Elizabeth fears Joaquin is overreacting because he regrets getting married so young.

When David wants to buy a car, he enlists Maria's help to convince Joaquin. He later regrets the decision after Maria teams up with a car saleswoman and they convince Joaquin to buy a car - for Maria. David then sets out to prove to his dad once and for all that women are constantly manipulating him.
