DS Lisa Swain (Vicky Myers) and Carla Connor (Alison King) are left horrified in upcoming Coronation Street scenes when they are faced with a shocking confession.

Lisa is still extremely busy with her attempts to bring down Joel Deering (Calum Lill), and next week she and Dee-Dee Bailey (Channique Sterling-Brown) trawl through footage from the Bistro van’s dashcam in the hopes of finding something they can use.

Viewers will know that Joel attacked Lauren Bolton (Cait Fitton) after grooming her and countless other young girls. After discovering that Lauren was pregnant with his baby, he drugged her with pills to induce early labour.

As Dee-Dee and Lisa search through the camera footage, they are hoping to trace the company that supplied the drugs to Joel.

They manage to ascertain that the parcel came from a private health clinic, and Lisa is soon in contact with them in a bid to find out details of the sender, but is the package enough to be used as evidence against Joel?
