George Lopez is a successful energy drink entrepreneur, a divorced father, and a history teacher who works at night. He is encouraged by his cousin and uncle to get back into dating.

George and Mackenzie have different ideas about the kind of birthday party that Harper should have, so George goes behind Mackenzie's back with his idea, which leads to disaster.

It is George's day to take care of Harper; however, he has to work, which leaves Harper with the short-tempered Alma. Also, George reluctantly asks Danny to do electrical work on his house.

Alma begins to question whether Harper is actually George's son, so she wants George to take a paternity test to prove otherwise. Furthermore, George fears that he and Harper have nothing in common.

George makes Danny get a prostate exam, and - after signing his will - George begins to believe in old superstitions that his death is near.

Alma slips on the kitchen floor, so George is forced to take care of her, which threatens a round of golf he has scheduled with his idol, Lee Trevino.
