Rework: After an interstellar super-freighter goes missing and crew are murdered, an exasperated Homicide Investigator must overcome personal and professional obstacles to solve the whole case.

The logline seems vague in its descriptions.

What does "...must overcome personal and professional obstacles..." mean? How will this propel the plot forward? More importantly, why MUST he overcome this stuff in order to solve the case?

Lastly, in all the versions you've posted of this cocnept I still can't see how a cop solving a criminal case is story worthy? What sets this apart from all the other cop chasing criminal movies? You would need to tie in a personal stake for the MC, cliche as it may be, a stakes character would do you a world of good here. Could his brother or sister have been a member of the crew?

If it's missing, how does the MC know the crew got murdered?

I think personal and professional obstacles is not specific enough.
An unhappy marriage or a distant child make it more primal,I mean anybody can understand that problems with loved ones is something that makes things harder.

The logline doesn't present something that sets this story apart from all the other ?police investigation stories. Other than putting it space. Is there a way to make the SciFi elements of this story more integral to the plot? What's the hook?
