Academy Award winning eccentric inventor Wallace, and his faithful, four-legged friend Gromit have specially re-mastered all four of their smashing half hour specials. Love blossoms in the course of Wallace and Gromit's latest business, the Wash 'n' Go Windowcleaning Service, when they are called out to clean the windows of the attractive Wendolene Ramsbottom. Little do they know that a lamb, Shaun is hiding in their house after escaping from the clutches of evil sheep rustlers. Preston, the monstrous dog-butler who lives with Wendolene hatches a plot to steal the blueprints for Wallace's latest invention, the Knitomatic machine. Preston adds a mincing device to the washing, shearing and knitting contraptions and schemes to install the new contraption in his dog-food factory. Gromit is on the trail, but before he can alert the love-struck Wallace to these dastardly plans he is framed by Preston and receives a life sentence for sheep abductions. Will this be the end of one of one of the most successful comic partnerships of all time, or will Wallace succeed in his attempt to save Gromit and bring the real culprit to justice?
