Here's what NETFLIX says about it:
When she loses her beloved husband, Gerry, to a brain tumor, grieving widow Holly Kennedy learns that he left a series of letters behind to help her cope with the pain of living without him.
Very sweet movie! I loved how much he did for her to help her move on after he passed. He really went to a lot of effort and time and he really meant his love for her! Made me smile although I don't think there are any men out here who could live up to this expectation!!
