Frank (Andrew Lancel) will soon be found dead at Underworld after upsetting a number of Weatherfield's residents, leaving police baffled as they try to discover who the culprit was.
The businessman's body remains at the factory while police investigate the scene, and when it is finally removed the next day, Carla (Alison King) and Michelle (Kym Marsh) watch on - seemingly horrified.
In the days that follow, Carla finds herself firmly in the frame for the crime - having the biggest motive after Frank sexually assaulted her and conned her out of Underworld.
When it emerges that the new factory contract is mysteriously missing from Frank's desk, the scrutiny surrounding Carla intensifies. As the police believe that Carla killed Frank and retrieved the contract to keep hold of Underworld, she quickly becomes their prime suspect.
However, Michelle soon has a shocking confession to make - telling Carla that she returned to the factory on the night of Frank's murder and stole the document.
As this puts Michelle at the scene of the crime when Frank died, the ladies decide to set fire to the paperwork. With the pair conspiring together, could either of them have been the killer?
