Hi, Vikki Harris. For a logline, you want something like: "After ______ (something happens/the inciting incident), a _______ (the protagonist with an adjective) tries to _______ (goal of story) so ________ (stakes)."

Loglines are one or two sentences. You can add the antagonist in the logline. The inciting incident can also be at the end of the logline.

Example #1:

"After a group of dog criminals arrives in a small town, an impulsive dog sheriff defends a dog treat factory so they won't steal food that's meant for hungry dog families."

Example #2:

"A dysfunctional couple works together to survive against bears after they crash on an abandoned road miles from help."

NOTE: Not all stories will follow this logline template. Biopics, TV shows (the logline for a show might not follow this template, but the logline for an episode in the show could), and documentaries might not follow this template.

Hi, Maurice Vaughan. Thank you for your comment. This is a logline for a television pilot.

Ok, Vikki Harris. I think the logline needs some work. Mainly the first part of it. The first part is a list. Since your logline is for a pilot, the logline can follow the logline template I commented about earlier.

Two Lives. Two Families. Two Concepts, nature vs. nurture. After an accidental switch-at-birth incident is revealed, two families try to navigate through the havoc unleashed on their lives, so that they can bond together as families. (I like the beginning list think; it draws attention and sets the stage)

I like that logline better, Vikki Harris! I think "Two Lives. Two Families. Two Concepts, nature vs. nurture." distracts from the logline. Suggestion: You could put that line in the synopsis area.
