The Winx split up again on two missions. Stella, Tecna and Aisha track down Matt to the fashion school, while Bloom, Flora and Musa try to free Hook's pirates from the shadow creature's traps. At the fashion school, Stella encounters her nemesis, Obscura, who traps her in a world of isolation and has her re-live her innermost fears of being alone and verbally bullied by everyone.
