Mr. Loud tells his daughters that today is "Take Your Daughter to Work Day", and the sisters ecstatically join in. Unfortunately for Lincoln, he is the only one not allowed to come along, since he is a son. Feeling bad for Lincoln, Rita (Mrs. Loud) says that she's declaring today "Take Your Son to Work Day", and Lincoln, although hesitant at first, decides to join in after being told that he can make any situation fun.
At the dentist's office, Rita tells Lincoln that he can pass the time by exploring the different rooms of the building, use the dental equipment, and play with the fish in the tank. Lincoln tries his best to entertain himself, only to get discouraged when he sees his sisters having a great time at Mr. Loud's office, which happens to be located right across the street. Just as Lincoln bemoans on how he'll never have as much as them, he discovers that there's an arcade located right next to Mr. Loud's office building, and decides to go there. However, before he leaves, Rita asks him to look over a notebook of hers that contains a novel she is working on, not wanting it to get damaged.
As Lincoln plays at the arcade, he discovers that he has to get back at the office. Upon arriving back to the dentist's office, Lincoln realizes he left Rita's notebook at the arcade. To Lincoln's relief, Rita says that she has to work on a patient just a bit longer, and he decides to use that extra time to get it back. Arriving back to the arcade, Lincoln realizes too late that the garbageman has arrived, and dumped the notebook into the truck. What ensues is Lincoln running around town desperately trying to get the notebook back, only for it to end up in a different predicament every time, and Lincoln having to resort to numerous tactics to get it back. Lincoln finally gets a hold of the notebook at a construction site.
Lincoln arrives back to the dentist's office (with cement shoes), and is prepared to give Rita's notebook back. However, the chase to get the notebook back has heavily damaged it, and it crumbles the second he hands it back. When Rita asks how this happened, Lincoln tells her the whole story, and Rita, while initially upset that Lincoln lied to her, says that he might have actually helped her out, since she believes that the initial idea for her story wasn't good enough, and that Lincoln's adventure today could be a much more entertaining story. When Rita asks how the adventure went, Lincoln says that he has a better idea on how to tell the story.
At the end of the day, Mr. Loud and his daughters return home and start to feel sorry for Lincoln, since they think that he had a boring day. However, at that exact moment, Lincoln and Rita come by, riding on skates while being pulled by a horse, revealing that Lincoln has opted to reenact his adventure to show his mother first hand what he went through. This leaves the sisters slack-jawed in utter awe when they see how Lincoln is having even more fun than they had.
