Next week, EastEnders viewers will be on the edge of their seats as Penny Branning's debut club night at Peggy's takes a terrifying turn for the worse. The disaster leaves one Walford resident burdened with guilt. As regular watchers of the BBC One soap are aware, Penny (portrayed by Kitty Castledine) secured the role of managing Peggy's after Phil Mitchell (Steve McFadden) found Chelsea Fox (Zaraah Abrahams) drinking while on duty.
Penny declined to return Chelsea her managerial position, assuring her boss Phil that she would organise successful club nights at the bar. However, when Penny's big club night comes around next week, she is caught off guard and attempts to sell some last-minute tickets. Chelsea seizes this chance to exact revenge and plots to sabotage her competitor.
Despite the venue being nearly full, Chelsea interferes with the booking system and releases more tickets for sale online. In another part of town, at The Queen Vic, Kim Fox (Tameka Empson) informs Jack Branning (Scott Maslen) that his estranged wife Denise (Diane Parish) has begun finalising their divorce proceedings.
