Lynda Carter in Wonder Woman (1975), “Time Bomb”

Cassandra Loren uses a Time Portal to travel from 2155 back to 1978 and make herself a fortune in a time when that still meant something. Adam Clement, the Time Portal’s inventor, follows Cassandra in order to stop her. He is quick to contact the I.A.D.C. (because his grandfather worked for them around the year 2000) and Diana Prince in particular.
