WHO FEELS IT KNOWS IT – A couple of high schoolers spend their 4 days of Senior Trip to Jamaica looking for the ghost of Bob Marley.

Agreed with the above.

Their motivations are not clear, what was the inciting incident that made them need to find the ghost?

As CraigDGriffigths said.

Why do they need to look for the ghost? ?What's are the stakes? ?And who/what opposes them?

Don't really need to know how long the trips is. Why are they searching. Use the few saved words and you are done.

Two teens wanting to ..... go to Jamaica to find the ghost of Bob Marley.

Who and their goal. Minimum for a logline.
