A blackout requires staff to treat patients without technology, so Bell orders the staff to stop accepting new patients. Conrad and Devon go against the mandate to help a child, and Mina and Austin must perform heart surgery.

Bell grows frustrated when Conrad's dad and new chairman of the board requests Conrad's input in his discussions about hospital expenses. A sharp and sophisticated medical device representative tries to promote her costly products.

In a final and drastic attempt to save Nic, Conrad calls in a favour from the one person he promised he never would. Micah is rushed back to Chastain with major heart complications.

Devon's doubts about his relationship reach a peak as his friends and family gather for his big wedding day; as Chastain's medical device company continues to succeed, Julian makes a discovery that leaves her uneasy about her involvement in it.

In an effort to save Chastain, Bell considers selling the hospital to a conglomerate, but Kit tries to make him see that the negatives will outweigh the positives. Nic tracks down Kyle and pleads for him to reconsider donating a kidney to Jessie.

Conrad goes head-to-head with Bell after he recommends a risky medical device. Meanwhile, Mina and Austin grow closer together, and Dr Hunter returns.
