As attractions simmer between the staff at a busy Perth hospital, four couples find their defenses falling and secrets revealed. Making time for romance is a challenge in this fast-paced, high-pressure environment. But risking it all for love turns out to be just what the doctor ordered.

Masquerade: Sophie Franklyn and Alex Scavoni spend a sizzling New Year's Eve in each other's arms, reveling in the anonymity of a masked party. The next time the two meet, it's in the high pressure world of emergency room medicine where they must work side by side.

Rescuing Dawn: Nurse Dawn Granger has loved and lost and it's a road she's not prepared to travel again - that is until paramedic Andrew Holmes reappears and makes her question feelings she thought long dead.

Seducing Phoebe: Phoebe Fitzgerald is about to marry a wonderful man - until her ex turns up and declares his undying love for her. Confused about her feelings, she calls off her wedding to Marco Petronelli. Can Marco convince her their relationship is worth saving?

Trapped by Cupid: Nurse Lisa Wheeler wouldn't mind getting swept off her feet this Valentine's Day, but she's stuck working the late shift with arrogant Dr. Noah Collins. When this couple gets stuck in a stalled elevator, it turns out the ER's golden boy might just have a secret soft side - and Cupid might have better aim than she thought.
