In the clearing behind her home, six-year-old Clare Abshire encounters 36-year-old time traveler Henry DeTamble for the first time. Fourteen years later, an unexpected reunion at the library where he works gives Henry the opportunity to meet Clare – and their love story begins...again.

After a rocky start, Clare struggles to rectify this version of Henry with the man she's known - and loved - all her life.

After meeting her soulmate at age six, Clare laments a linear lifetime defined by waiting for Henry's unpredictable appearances. Meanwhile, an incident at a high school party finds a distraught teenage Clare turning to Henry for help.

Clare hosts a couples’ dinner party to introduce Henry to her roommate Charisse and best friend Gomez, but when it’s crashed by another Henry and his girlfriend Ingrid, deeply held secrets are revealed. Meanwhile, Clare remains determined to make her 18th birthday – and fated 152nd meeting with Henry in the clearing – unforgettable.

Despite years spent together in the clearing, Henry finally has a chance to step inside Clare’s home – and meet her difficult-to-please family for the first time. Meanwhile, Henry and Gomez’s path to best friendship is anything but straightforward.

With his and Clare’s wedding day fast approaching, a high-stress Henry suddenly begins to travel more than ever and grows increasingly desperate to find a solution – even if it means leaning on his estranged father, Richard. Meanwhile, Clare is devastated by a shocking blow to the future she envisioned with Henry.
