When Frank's mother Anne (Gwen Taylor) discovers that Carla freaked out with Rory last night and lost the business a big order, she declares that her son's ex-fiancée is a complete liability.
Carla's (Alison King) erratic behaviour later continues as she sends everyone home from the factory, unable to cope with the pressure that she's under.
Deciding that she can't let Frank's business go under and keen for revenge following the rape allegation, Anne sends in removal men to take away her son's share of the factory - including machinery and materials. How will Carla deal with this latest crisis? And will Anne ever see Frank's true colours?
Coronation Street airs tonight at 7.30pm and 8.30pm on ITV1.
