While investigating a major meth laboratory, Charlie and Megan recover a hard drive belonging to the primary meth distributor. Unfortunately, the disk had been badly damaged by the explosion of the meth lab. In spite of that - and luckily for the investigators - in many cases it is still possible to recover data on a badly damaged drive by making use of a computer's built-in redundancy in data. Essentially, even large portions of the files on a drive are lost or erased, because of symmetry and redundancy in most modern data storage, Charlie had a chance!
In this episode, Charlie uses information theory and information entropy to help understand the manifesto and probabilistic graph theory in an attempt to determine where the perpetrator is likely to be found.
Mr. Bean goes to the beach and tries to change into his swimming trunks without ever becoming naked, in order to prevent a nearby man from seeing him. Mr. Bean goes through great pains to successfully perform this task. Afterwards, he becomes aware of the man's handicap.
