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.

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.

After David and Sarah break up, David takes Maria's cheerleader friend Paula on a date, much to the dismay of Joaquin, who plots to get David and Sarah back together. Meanwhile, Elizabeth sets Ernesto up with one of her crazy co-workers.
