Two babies are abandoned in a Montreal orphanage in the winter of 1914. Before long, their talents emerge: Pierrot is a piano prodigy; Rose lights up even the dreariest room with her dancing and comedy. As they travel around the city performing clown routines, the children fall in love with each other and dream up a plan for the most extraordinary and seductive circus show the world has ever seen. Separated as teenagers, sent off to work as servants during the Great Depression, both descend into the city's underworld, dabbling in sex, drugs and theft in order to survive. But when Rose and Pierrot finally reunite beneath the snowflakes the possibilities of their childhood dreams are renewed, and they'll go to extreme lengths to make them come true.
