Twenty-seven-year-old Daisy already beat breast cancer three years ago. How can this be happening to her again?

On the eve of what was supposed to be a triumphant “Cancerversary” with her husband Jack to celebrate three years of being cancer-free, Daisy suffers a devastating blow: Her doctor tells her that the cancer is back, but this time it’s an aggressive stage-IV diagnosis. She may have as few as four months left to live. Having already endured brutal rounds of chemo and radiation in her early 20s, Daisy decides that she doesn’t want to go through it all over again --- especially when the odds are already stacked against her. Instead, she forgoes treatment and focuses on what suddenly becomes her most pressing concern: What will happen to her brilliant but otherwise charmingly helpless husband when she’s no longer there to take care of him?

This alarming thought sparks a selfless undertaking: Daisy decides that in the time she has left, she needs to find her husband a “replacement wife” who can be there for him when her time comes. After scouting the local singles scene in her hometown of Athens, Georgia, and scouring online dating sites unbeknownst to Jack, Daisy finds the perfect match…only to realize that this potential “replacement” already volunteers at the animal hospital where Jack works as a vet-in-training. Suddenly, as the reality of seeing her husband with another (decidedly more compatible) woman becomes all too real, Daisy regrets having set everything in motion in the first place…but is it too late to take it all back?
