Marty had a heart condition that made her pass out every day. Adele was a cardiac alert service dog who could literally sense the beating of Marty's heart and save her from fainting. They were the perfect team. They were soulmates. But nothing can last forever, and as the time comes for Adele's retirement, Marty must figure out how to let go of her best friend and find a new partner who can take over the job of protecting her heart. With Adele by her side, Marty went from being unable to walk around the block without passing out, to leading an adventurous, joy-filled life as a wife, mother and artist. She doesn't want to go back to how it was before Adele, but going forward is just as scary. The film follows Marty and Adele on the rocky, painful, but ultimately life-affirming journey to letting go.
