An ex-con sets out to kill the reformed paedophile who he believes murdered his child, only to fall for the man’s protective sister.

Some of my comments on your previous version are now rendered redundant hahaha!

What happens after he falls for the sister? What's his new goal? Like I mentioned in the previous version of this logline, is the relationship with the sister the A-story or the B-story?

Maybe something like (from the MPR):

but when he discovers the real truth the ex-con must protect the sex offender from a community that despises him.

My attempt isn't perfect by any stretch ... but I think since the story is primarily about the two convicts (which I think is great) it's important to keep that front and centre.

Loglines I'm experimenting with...

1.? An ex-con sets out to kill the paedophile who molested him as a child only to fall for the man's protective sister. - DPG's one.

2. An ex-con sets out to kill a reformed paedophile whom he believes is responsible for the disappearances of several children.

- edging towards thriller territory here. This one is very weak.

3. An ex-con sets out to kill the reformed paedophile who he believes murdered his child, only to fall for the man's protective sister.

- I like this one the most just because the goal is very specific and I think the conflict pops.

4. An ex-con, defending a reformed paedophile from an angry mob ? begins to doubt the man's innocence. -? mikepedley's idea.
