A box of possessions.
A father with no memory.
A daughter with just one day to piece together the past.
When Sabrina Boggs stumbles upon a mysterious collection of her father's belongings, her seemingly uneventful life suddenly alters and shifts.
In the single day she has to search for answers about the man she thought she knew, a man who can no longer remember his own story, Sabrina uncovers far bigger secrets than she could have imagined. And discovers that sometimes it's the people closest to us that we know the least.
