After being framed for the murder of his father, a teen boy growing up in the late 1930’s finds comfort in the “Red-Ryder” comic strip. In his adventures he struggles to find his father’s murderer, and prove his name is clear.

In relation to the last comment, I don't think the log line means he needs to be living in his own comic strip. I took it to mean more that the kid gets inspired by the hero, and tries to emulate him while trying to clear his Father's name.
Could have some good stuff in it. The kid starts dressing up, nosing around crime scenes (trusty side kick pet dog?) and unbelievably is able to stumble upon some good evidence.

Good luck!

Hi,

Just a few thoughts/questions that spring to mind when reading your logline:

Is it the case that he believes he is actually part of this comic strip? As in, does his imagination get the better of him?
If he's been framed for murder does that mean he is in prison - in which case - how does he work to solve the case of the real murderer?
The wording is a tad confusing "in his adventures he struggles to find his fathers murderer, and prove his name clear" - this makes me think he is going on adventures but at the same time that it's all just in his head, as a character in the comic strips.

I think the confusion comes in through the disconnect between the boy enjoying the comic and trying to find his fathers murderer. Perhaps if the connection was clear or it was clearer how the comic book aided his journey it would help.

I hope this makes sense / helps.

Thanks and good luck
