A couple with a criminal past, try to start again in a cop neighbourhood, but when children start going missing, they suspect their neighbour — and set out to prove it.

A couple with a criminal past, try to start again in a cop neighbourhood, but when children start going missing, they suspect their neighbour ? and set out to prove it.?

I think what's missing here might be the goal isn't strong enough.

Perhaps if their kid went missing instead?

I mean I think it's fine but not exactly "wow".

I considered putting "reputable" in front of neighbour - but I want to keep it lean.

I added a more solid inciting incident.

Okay. I chopped of the other "cop". We don't need two.

I'm keeping the "trying to start again" as opposed to "start again" - for now anyways.
