At first Simon doesn't recognize Gordo but after a series of uninvited encounters and mysterious gifts prove troubling, a horrifying secret from the past is uncovered after more than 20 years. As Robyn learns the unsettling truth about what happened between Simon and Gordo, she starts to contemplate: how well do we really know those closest to us, and are bygones ever really bygones?
