Hi, India. For a logline, avoid don't start with "About" or that word in an introductory phrase at all. You want to set forth four things in your logline and make sure it's as short and as intriguing as possible. The four things are:

Protagonist (with at least one adjective to describe her)

The antagonist

The main goal or desire of the protagonist

The main obstacles to the protagonist in reaching said goal

Hope this helps!
