Hi Matina
Way to much is happening here. This come across more as a synopsis than a logline.
Best advice refer to Karel's notes, you can find them at the head of the page. Also have a read of other peoples loglines and comments.
A logline is made up of the following components:
? the Hero's function or job
? the Hero's weakness and/or how it's overcome (optional)
? the story's first major event or ?Inciting Incident? (optional)
? the Hero's main goal in the story
? the Antagonist or obstacle(s)
? the stakes (unless implied in the goal/obstacle)
Depending on the purpose of the logline, you will include less or more. The logline in its simplest formula is this: When [a major event happens], [the Hero], must [do the main action].
JAWS:
? Major event: a swimmer is brutally killed by a shark
? Hero (function): a sheriff
? Main action: stop the killing monster
JAWS Logline:
When a swimmer is brutally killed by a shark, the local sheriff must stop the killing monster.
Best of luck!
