Single mom and veterinarian Natalie DeAngelo lost everything the day her two sons were killed in a school shooting. Following her psychiatrist's advice, she decides to sell her once-happy home to escape the immense pain and grief of living there alone.

Desperate to find relief from her unspeakable loss, Natalie impetuously commits to honoring her boys' memory and volunteers to assist philanthropist Andrew Gordon at his elephant sanctuary in northern Thailand. All she wants once she gets there is relief.

But she soon realizes she may be in over her head when she faces three major challenges: her debilitating PTSD is creating night terrors; Peter Hatcher, the sanctuary's irascible in-house vet, has a longtime grudge against her and wants desperately for her to fail; and Sophie, a female elephant with a raging leg infection and PTSD caused by human abuse, is demanding that Natalie use every trick in her veterinarian's black bag to heal her.

Dr. Hatcher wants to euthanize Sophie, as he claims she's a lost cause, and Natalie knows she must find a way to convince the others to let her keep trying. Can she and Sophie find a way to heal together and learn to love life again? Or will another tragedy shatter Natalie's progress?
