The one-minute trail is for Skins Fire - the first of three stories catching up with the show's characters.
Skins Fire follows Effy (Kaya Scodelario) as she lands a job in the financial world and uncovers evidence of a major fraud, sending her life spiralling out of control.
Fellow Skins regulars Lily Loveless (Naomi) and Kathryn Prescott (Emily) - plus guest stars Kayvan Novak and Craig Roberts - also feature in the new promo.
Two more films - Skins Pure and Skins Rise - will follow, focusing on the characters of Cassie (Hannah Murray) and Cook (Jack O'Connell).
Skins returns to E4 on Monday, July 1 at 10pm.
