According to E! News, the series will surround Kathryn (Sarah Michelle Gellar) and her plan to control her nephew Bash, the son of Annette Hargrove (originally played by Reese Witherspoon) and the late Sebastian Valmont (played by Ryan Phillippe).

It wouldn't be "Cruel Intentions" without a plot twist: married to newly-rich Pascal Barret, Kathryn tries to juggle a full plate as she tries to take over a company, in addition to her own nephew, reports Deadline Hollywood.
