Lincoln hatches a plan to capture the "perfect" family photograph for his parents' anniversary gift.
Lincoln has created a homemade coffee mug as an anniversary gift for his parents every year, but his sisters believe it to be a lame gift, with Lola accidentally blurting out that Mom and Dad put his "mugs" in the attic without his knowledge. When he goes into the attic to see if this is true, he discovers that Lola was right, as all the "mugs" Lincoln made in the past are stored away. As a heartbroken Lincoln worries about what he can give to his parents now, he finds Dad's old camera, and gets the idea to take a family portrait to give to his parents.
Lincoln gathers the girls in the backyard for the photo shoot, and they all hold a smile, as Lincoln sets the automatic timer. However, they get bored after a few seconds and go do their usual antics, as the picture gets taken, much to Lincoln's frustration. Feeling the photo isn't "perfect", Lincoln uses various methods to convince his sisters to take part in a new photo. As he does, he alters their appearances, stifles their natural habits, and puts matching sweaters on them.
As the timer is set, Lori asks Lincoln what was wrong with the other photo and he nervously admits that they acted too much like themselves. Everyone is deeply offended by his thoughts of them, so they decide to put on "perfect" smiles for the camera out of spite for him. After the camera takes the picture, the girls leave Lincoln, apparently in a flash. As Lincoln walks through the house, looking at the new picture and observing his sisters' true personalities, he sees how happy they are and begins to realize that his new picture of them doesn't reflect on who they really are.
When the time comes to give Mom and Dad their present, Lincoln ends up giving the old photo instead of the "perfect" one. They love it so much that they decide to hang it above the mantle for all to see. Lincoln apologizes and says to sisters that their true selves are perfect enough for him, and they embrace in a group hug. However, as a final rub-in, Lincoln tells them they might as well put their gifts in the coffee mug box, since their gifts will pale in comparison to his, which angers them into arguing with him... just the way he likes it.
