JESSICA McHardy was a modern-day damsel in distress when her car began floating in floodwater.
Suddenly a mysterious man swam to her aid, took her hand and led her to safety.
He then disappeared before Jessica had a chance to thank him and now she's searching for her hero.
The 18-year-old from Caloundra was on her way home from a chemistry lecture at the University of the Sunshine Coast on March 22 when she lost control of her car on the Nicklin Way at Warana.
"I just turned off from where 7Eleven is. It was raining so hard I couldn't see two metres in front of me," she said.
"All this water splashed up on my car and I realised I was in floodwaters. I couldn't turn around, so I thought, 'Okay I'll have to try and get through it', hoping it gets lower.
"It only got worse the further I kept going. I started accelerating a bit more, I revved it and it didn't move.
"I pulled over as much as I could off the Nicklin Way. I tried again and it just stalled and didn't start again.
"I was freaking out and called my mum. I was screaming on the phone and gave her the biggest fright."
Then Jessica's unknown saviour came to her aid.
"I saw this guy coming through floodwaters. He came and said, 'You need to leave your car, leave the handbrake on'," she said.
"The car was moving. Water was coming under the door. That's when I freaked out.
"The guy said, 'You have to come with me, I'm going to open the door, take my hand and come with me'.
"He opened the door and grabbed my hand and helped me through floodwaters and took me around the block to a safe level.
"I was so flustered and didn't even have time to thank him or even know what was happening. He was pretty much a hero.
"I want to say thank you. If I ever found him I'd buy him a few beers.
"I owe him big time.
"My parents are so thankful he came to my rescue."
