A sound effects man teams up with a cop has seven days to go after a murder suspect who killed a teenage girl who happens to be his daughter.

I revised it.

This is basically Taken with two protagonists teaming up to get the murder of a daughter.

• What does the profession "sound effecte" have to do with your story? Does it play a role in getting the suspect murder? I don't see a connection here.

• Why does he have seven days? What's happening after the seven days? The time restriction is not clear to me without a description.

• You say he is a "murder suspect", but after you write "who killed a teenage girl". So is he a suspect or is he the real murder? That's important to understand.

I like the title of your logline. Sounds very exciting!
