Pleased that everything is coming together as planned, Charlie is also thrilled that Drake's confidence in her brother Seth, who's managing the tennis center, has not been misplaced. However, her faith in Drake's childhood friend Neil White wavers when the sexy musician turns up the heat in pursuing Charlie's sister, Ceilia.
Tensions mount when Ceilia goes missing the night before the opening match. Although Charlie immediately suspects Neil, she later begins to question her sister's jealous ex-boyfriend Bryan Shepherd, a marketing guru who happens to be on the Winstead payroll.
Once Charlie locates her sister, she's surprised by how quickly Ceilia bonds with Oliver Hedges, an honored guest at the center's opening weekend. When Drake decides to add Oliver to Winstead's roster of tennis instructors, Seth also becomes a fan of the friendly Las Vegas transplant.
As time passes, Charlie must leave Drake for an out-of-town photo shoot. After several past threats to her safety, Drake doesn't want her to travel alone, but Charlie insists she'll be fine. When Drake finally gives in and lets her go, the stage is set, and someone watching finds their perfect opportunity for revenge.
