The standard operating procedure of the TV sci-fi series
Quantum Leap was to show physicist Samuel Beckett travelling backward and forward in time, "leaping" into the personalities of others, in the hopes of altering the fate of those others. In the series' 1990-91 season opener, "The Leap Home", Dr. Beckett assumes his own personality-that is, he becomes 16-year-old Indiana farm boy Sam Beckett in the year 1969. Armed with foreknowledge, Sam endeavors to keep his sister (Carolina Kava) from marrying a number-one jerk, to prevent his the death of his brother (David Newsom) in Vietnam, and to try to save his father from succumbing to a heart attack. Series star Scott Bakula plays both Sam Beckett and Sam's dad. "The Leap Home" originally aired September 28, 1990. ~ Hal Erickson, All Movie Guide
