Synopsis
A day at the fair turns out to be anything but fun when Robyn skives off work to enjoy the rides with old school friend Fran, who seems to spend most of her time putting the student nurse down. But after an accident on the ghost train involving a spaced-out drug addict in an Easter bunny suit, she has more to worry about than playing truant from work. Can she save her friend's life? Meanwhile, one of the ride owners collapses and is rushed into the ED, where Ash diagnoses a tumour, while Tom finds himself in hot water with both Sam and Zoe.
