When the devastation of her sister Holly’s death trickles into her workplace, Sam finds an unexpected connection with her coworker Joel. Later, just as a fight with her other sister Tricia leaves Sam feeling further unmoored, Joel offers her a lifeline.

Sam begins to bond with fellow members of Choir Practice, but her burgeoning friendship with Joel is threatened over competing outlooks on their future in Kansas. After a disappointing job review and a concerning visit to her parents’ house, an increasingly distraught Sam seeks help from someone close to Holly.

With a tornado looming, Sam prepares for a different kind of storm as she shares the truth about Rick with Tricia. After impulsively adopting a dog, Joel realizes he wants more out of life.

After a surprising update concerning her recent job performance, Sam must evaluate her next step. Meanwhile, Tricia and Charity’s working relationship grows complicated, and a visit to Mary Jo in rehab brings some difficult family truths to light.

Distancing herself from Joel, Sam concentrates on helping Tricia with her blossoming pillow business – which soon faces sabotage from Charity. Meanwhile, Fred attempts to play peacemaker with Sam and Joel.

After reuniting with Joel at a funeral, Sam takes stock of herself and her actions – and decides to make things right with her best friend. Then, everyone comes together for an epic celebration of love and partnership at Fred and Susan’s wedding.
