Samantha Callen (Shannon Sturges) is an accountant who must determine whether Dr. Branson's project warrants more funding. Jake must try to convince Samantha that the machine is worthwhile. During the process, Jake and Samantha become romantically attracted, but powerful tornadoes threaten the lives of all the major characters.
