Hi Don Curbow --
Whilst I find elements to this intriguing, overall I am left pretty clueless as to what actually happens in this story.. 'distant psychotic father...' ?? -- does this mean his father is psychotic, but lives on the other side of the world, or is just emotionally distant (due to him being psychotic?)... 'spurs a renewed connection...' -- a connection to who? His father?.. and why is it renewed? Were they estranged?...
"...visions of his murder" -- who's murder? The protag or his father??
In all, there's just too many questions that go begging at the moment.
There are many rules that go along with creating a logline; some are there for good reason, some are worth breaking -- but for mine, the most important rule, one than cannot afford to be broken is: it has to make sense...
Below is just my spin, taking obvious liberties etc...:
'A disgraced ex-cop seeks redemption over his children's deaths after discovering his father's paintings are precognitive depictions of unsolved murders, including the murder of his children by his estranged wife.'
