Roy and Hayley Cropper - played by David Neilson and Julie Hesmondhalgh respectively - will jet off to Romania when a face from their past invites them to attend her lavish wedding to Romanian football star Dean Fraser.
Although the odd couple's Transylvanian trip goes from bad to worse when a problematic flight causes them to miss the nuptials, they look forward to the prospect of a break at their luxury Eastern European villa.
However, despite their best intentions, their quiet break is disrupted by the arrival of brash couple Verity and Glen, who claim to be Dean's aunt and uncle.
Unable to stand Glen and Verity's vulgar antics, Roy and Hayley quickly cut short their break and return to Weatherfield, but events soon take a surprise twist when they stumble across their surrogate daughter Becky Granger (Katherine Kelly).
Filming is due to begin in the summer in time for a Christmas release of the DVD.
