Kiera and Carlos investigate the theft of a truckload of waste from a chemical plant. By itself, the waste isn't particularly dangerous but when combined with a series of simple household chemicals, it can turn into a deadly gas. They know from the security tapes that Liber8 is behind the theft and can only assume that there will soon be a terrorist attack. Liber8 has something else in mind. Meanwhile, Alec from the future time-line is appalled at what he sees in the present day version of himself. He tells Kiera that he and Emily are simply going to go away and live their lives. First however, he will have to impersonate his present day self to get whatever information the other Alec has on Emily.
