Fans of Hollyoaks are in for a dramatic autumn as a new trailer for the 2026 episodes has been released, teasing a host of intense storylines. The preview highlights the return of Sienna Blake (Anna Passey), who reenters the village after serving time in prison. Her arrival is met with tension, especially given her past conflicts with Cleo McQueen (Nadine Mulkerrin). The trailer also introduces a surprising romantic connection between Sienna and Tony Hutchinson (Nick Pickard), who had previously left the village after the death of his wife, Diane. The mystery surrounding the disappearance of Ste Hay (Kieron Richardson) remains unresolved, with several characters, including James Nightingale (Gregory Finnegan), Lucas (Oscar Curtis), Sienna, and Gemma Johnson (Tisha Merry), suspected of involvement. James insists on his innocence and is actively searching for Ste, while Lucas is trying to prove he has changed and wants no part in his father’s past. Tensions rise when Leah Barnes (Charlotte Riley) falls down the stairs after a confrontation with Lucas, casting doubt on his account of events. Meanwhile, Cleo McQueen demands Dodger make a choice between her and Theresa, and the trailer hints at heartbreak for Theresa as Dodger appears to leave with Cleo. This decision, however, is not yet confirmed as final. Sienna’s return is expected to add further layers of conflict to the already complex dynamics in the village. Other storylines include the revelation that Cindy is the biological mother of Maddox, a truth uncovered by Dee Dee. This discovery shocks Maddox and Beth, potentially causing significant rifts within the Keanes family. At the same time, Jonah is revealed to be putting Caleb in danger to prevent him from leaving the village, which threatens both Caleb’s health and his relationship with Frankie. The trailer also highlights romantic moments, such as a surprise kiss between Sienna and Tony, and scenes involving Warren and Gemma, as well as Mercedes and Jenson. Additional drama unfolds with newcomer Abigail Matthews showing inappropriate interest in Dee Dee at Hollyoaks High, leading to escalating tensions during a parent-teacher meeting. Meanwhile, Kathleen-Angel is seen anxiously awaiting the results of a pregnancy test, with Ant waiting outside, adding to the suspense. The Hollyoaks Autumn 2026 episodes will be available on Channel 4's streaming platform from 6am on Mondays to Wednesdays, or viewers can watch them on TV at 7pm on E4.
