The day starts out innocently enough: The Boss is driving to work while listening to a self-help tape and so enraptured is he that he runs over several people and generally makes a menace of himself. Meanwhile a blood drive is taking place at work and Dilbert is the only suitable candidate to drain. So, after giving many, many pints of blood, Dilbert tries to drive home -- seriously impaired by his lack of bodily fluids and is arrested. While he is driving home, the blood drive nurse and the Boss, who has now arrived at work, drop, ALA water balloon style, a bag of Dilbert's blood on some unsuspecting workers below. This, in turn, sets up Dilbert's DNA as being at the scene of a crime, even though he didn't sniper off the workers he is accused of killing. Dilbert is sent to prison and while there organizes the prisoners into a model group of efficiency thugs. And, Alice, engaged to a prisoner on death row, attends her wedding, only to pull the electric switch after saying I Do.
