It's 1956, and working-mother Ava Lark and her son, Lewis, have rented a house in a less-than-welcoming Boston suburb. There, Lewis finds he is only able to befriend the other fatherless kids on the block, Jimmy and Rose. But when Jimmy goes missing, neighborhood paranoia ramps to new heights, further ostracizing Ava and Lewis.
Lewis never recovers from the loss of his childhood friend. In his twenties, he is a failure in love, living without direction, estranged from his mother. When Jimmy's disappearance is unexpectedly solved, however, Lewis, Rose, and Ava are thrown together once more to try to untangle the remaining pieces of the puzzle and reclaim something of what they have lost.
