"She believes her own truths and she lives in such a small world because she can't go outside and expose herself and be found out," Schmidt says.
"So Eliot and her mother are her world and her life - and she was used to being everyone's focus and getting a lot of attention."
Shelly's mum Bev (Jennifer Ludlam) is desperate for her daughter to get back in shape and reclaim her glory, so she stages an intervention, confronting the blase and "in denial" Shelly about her obesity.
But it's not until Shelly sees her jilted former boyfriend and coach, Paul (Joel Tobeck), on television with an attractive new rowing protege, clearly making another bid for a gold medal, that she suddenly accepts her problem and decides to make a comeback.
"I'm not Shelly Bowman - I look like I ate Shelly Bowman," she sobs.
The self-pity doesn't last long though, with Shelly determined to get Paul back as her coach, and find a way to fit into a single-sculls boat again.
The project has been helmed by Schmidt and her long-time collaborator Stayci Taylor from the get-go, creating the storylines, characters and dialogue.
"We were thinking, 'Yeah we'd like to write a comedy, a real Kiwi comedy for the family'.
"And we were thinking, 'Oh yeah, well we're a sports-mad nation so what about rowing?"
"Then we were thinking we needed an obstacle, and I kind of looked down at my belly, and said to Stayci: 'What if she'd put on 60kg?'
"And we both started laughing."
"I think Shelly is a cross between an elite athlete and a clown," Schmidt says.
"All the characters are quite clown-like actually, and the great thing about Shelly is that she's only recently put on a lot of weight so she's sort of finding out that all of the assumptions she had about fat people are kind of wrong.
"So that's an interesting and quite an amusing journey."

This new series trots, canters and gallops through 200 years of Maori horse culture. Many of the passionate people interviewed speak of a strong spiritual connection with their horses, which is perhaps why most of them can ride bareback so effortlessly, ripping along beaches or through paddocks. Presented by Annabelle Lee-Harris, a Maori Television journalist, and co-produced by her sister, Michelle Lee (their mum is former politician Sandra Lee), the first episode visits Hokianga's Pawarenga beach where locals race each other in 600m beach sprints. The day ends with a gruelling cross-country race. Later, the series goes to the rodeo, delves into the whakapapa of the Kaimanawa wild horses, and visits Otaki Maori Racing Club, which was formed in 1886.

Drama pick: Siege
This week's Sunday Theatre is a dramatisation of the three-day stand-off between police and Napier gunman Jan Molenaar (Mark Mitchinson, Rage) in 2009. When police officers went to Molenaar's house to serve a search warrant for allegedly growing cannabis he opened fire, killing Senior Constable Len Snee and wounding two officers and his neighbour Lenny Holmwood.
Siege is based on police files, eye witness accounts, plus the incident inquiry and coroner's investigation. It focuses on those who survived, including Holmwood, who is credited with saving the two officers by distracting Molenaar so they could reach safety. Also on Tuesday, at 9.30pm on TV One, Siege: The Interviews is a one-hour documentary telling the survivors' stories.
