Tranchtenberg plays Casey Carley a brilliant high school science student who initially films figure skaters for her physics project which would help her get a scholarship from Harvard. But, as time passes by she learns it herself to understand the sport better thinking it would help her in her project but eventually falls for the sport and turns out to be a figure skater herself. All this despite her mum wanting her to get the scholarship and go to college after her high school. That's when she makes her mum realise that she has shattered her mum's dream and not hers. Her heart was always in figure skating. The movie is ,how she goes about achieving her passion.
This is one of my favourite scenes from the movie and has always brought tears to my eyes. Her mum comes to see her perform despite she being against her, it is this support that actually makes her win :)
