Two engineers, Aaron and Abe, supplement their day-jobs with entrepreneurial tech projects, working out of Aaron's garage. During one such research effort, involving electromagnetic reduction of objects' weight, the two men accidentally discover an 'A-to-B' causal loop side-effect: objects left in the weight-reducing field exhibit temporal anomalies, proceeding normally (from time 'A,' when the field was activated, to time 'B,' when the field is powered off), then backwards (from 'B' back to 'A') in a continuously repeating sequence, such that objects can leave the field in the present, or at some previous point.
