A new cohort of interns joins the Pines Hospital. This is their first day and their last chance. The interns are thrown in the deep end when a wild storm hits, flooding the hospital with casualties and cutting off the power. The young doctors must work together with program leader Gloria and maverick registrar Curtis to restore the hospital and its patients back to good health.

Ellie and Curtis are forced to bend the rules in a matter of life-and-death. Jimmy has no time to recover from his traumatic first day when paramedics deliver a young boy with severe internal bleeding.

Gloria's authority is challenged, Jimmy battles a medical mystery, and a wild night leads Lisa and Josh to unexpected places. Mia teaches Yosef a valuable lesson.

Gloria's on the warpath, Ellie breaks the rules, Jimmy and Josh bond, and a party at Lisa and Yosef's house changes everything.

Jimmy and Ellie are stuck together on night shift, a medical inquiry digs up the past, and Josh spirals out of control.

The interns face their biggest challenge yet, the mid term exams are fast approaching as Jimmy's heart and relationship is pushed to the limit.
