Heidi and Tim give the designers their next assignment: a two-look, resortwear mini collection for a fashion show that will take place on a floating runway. One designer is redeemed after a weak showing in the first assignment while another designer fails to wow the judges with original prints and is eliminated.

For the first time ever, two designers face-off against each other in an all or nothing battle. Using their fellow competitors as their design and production team -- as well as their models -- the competition on the runway comes down to the wire and ends with a result no one sees coming.
