A sweet woman stops by her OCD neighbor's house to deliver him his mail only to wake up on a table seeing her neighbor with surgical tools.

As Kriss said, As the logline stands, tt's more of a "concept" than a "story".

I think I'm becoming a fan of your work though.

This gives us a scene rather than an entire story. What is she going to have to do to escape? For all we know that is the end of the story so we need to know what she will have to do to escape.

'When a sweet elderly woman awakens on tied to her obsessive neighbours work table, she must find any means of escape before being surgically experimented on.'

Don't know if this helps but it gives more of a sense of a story instead of a scene.
