After her mother publicly humiliates her four-year-old son Theo at a family barbecue, declaring the fries were reserved for her “real grandchild,” Reagan takes her son to a diner instead, later sending her mother a single defiant word, “Remember,” in response to a barrage of calls demanding she come rescue her ailing father. The next day, her aunt Winifred summons her privately to reveal a hidden shoebox from her father’s belongings, one she says she can no longer carry the secret of.

Inside the box are yellowed envelopes addressed to Reagan in the unmistakable handwriting of Caleb, her son’s father, the man her mother claimed had vanished five years earlier during labor, suggesting an entire family history built on a lie Reagan never had the chance to question.
