A week before her debut at Fashion Week, key pieces from Ali's collection are stolen.

As Ali digs deep for inspiration, Marco investigates the theft as it looks like an inside job. If life wasn't hard enough for Ali, enter Jed Nicholls, her ex. After two years in New York, Jed is back and Ali's life is turned upside-down.

Having spent the last few years obsessing about him - the man who broke her heart - and is now finally forced to confront her demons when she bumps into him. Fortunately for Ali, she has her best friend, Alex, to support her.

That is until, on a hunch, Marco visits Davina's studio and spots Ali's stolen designs, placing Alex at the scene of crime. Sparks fly when Ali discovers Alex's game and kicks him out of their flat. Without her best friend there to protect her, Ali ends up making a total fool of herself by losing her cool with Jed at the launch of his new store.

Fed up with being kept in the dark, Chris has reached the end of his tether with Ali and pulls the plug on their relationship. At an all-time low, Ali focuses on her work but it's Mimi who gives Ali inspiration for her new collection for Fashion Week. Realising that she really needs Alex in her life, Ali finally forgives him.

Meanwhile, Marco has spotted an opportunity: with Chris no longer in the picture, could he be about to make a play for Ali's heart? And, as Mimi's affair with her boss takes a dramatic turn, her career as a stylist finally takes off.
