On her return to the past, Melissa discovers Mark Antony in a desperate state. Drunk and defeated and ousted from power, his confidence is shot. As he is about to embark on a difficult military campaign, Melissa must find a way to lift his spirits before he marches his army to its destruction. As old passions rise to the fore, will Melissa be able to set Mark Antony on the right path allowing destiny to be fulfilled, or will history be rewritten forevermore?
