Sarah Platt's plan to trap Coronation Street villain Callum Logan is set to backfire on her when he realises what she is up to and attacks her.
New pictures released of Sean Ward and Tina O'Brien in rehearsal offer a sneak peek into the opening scenes for the soap's highly anticipated live episode, celebrating 60 years of ITV.
Sarah lures the drug dealer to the Platts' house by sending a message from sister-in-law Kylie's phone, telling him they are ready to pay the £20,000 blackmail money he has demanded.
Sarah hopes to bring an end to Callum's hold over the family by recording everything he says to take to the police as evidence.
But Callum sees through her scheme and things take a sinister turn for the worse.
These are some of the opening scenes to the hour-long live episode, which will air at 7.30pm on Wednesday.
The episode will feature the culmination of Callum's reign of terror over the Platt family, along with Lloyd Mullaney and Andrea Beckett's leaving party in the Rovers, Roy Cropper and Cathy Matthews getting closer and Tim Metcalfe finding out about Sally Webster's secret kiss with her ex Kevin.
After the episode, Stephen Mulhern will interview the cast as they come off air and reveal behind-the-scenes secrets in a special show airing on ITV2 at 10pm.
