It's the epic finale! The last two standing take on their biggest challenge yet: choreographing routines for 50 dancers, and then the entire Dance 100.

Before the Dance 100 select their finalists, choreographers use 25 dancers to tell a story with a narrative dance. Will this be the end for a favorite?

It's a decade dance-off! For the first half of the semifinals, choreographers create routines for 25 dancers inspired by the '60s, '70s, '80s and '00s.

With 20 dancers in their crew, contestants must elevate their routines — literally. Those that can't rise to the challenge will have to dance battle.

When the number of dancers jumps to 14, the choreographers must incorporate a prop — but some contestants can't juggle the added pressure.

The competition kicks off with eight hopefuls choreographing routines for seven dancers. But will their moves be enough to impress the Dance 100?
