After an escaped convict forces a divorced mother to hide him, they fall in love and must flee to Canada to start a new life.

Yep would be tough as you'd need to portray the female as genuinely falling in love rather than suffering Stockholm syndrome.

This is a tough one to logline as the main dramatic point of view could be the woman's and could be the man's. Depending on which one you choose the inciting incident will change.
If it is the woman then it's the man?forcing her to hide him, if it is the man then it's his injury - it sounds like the love story is a subsequent B plot.

In other words, what is the hook?
