Synopsis

Team Flash hat zunächst keine Ahnung, wer Red Death ist. Doch bald gibt sich ihre neue Gegnerin als Ryan Wilder zu erkennen. Sie kommt aus einer anderen Zeitlinie und hat einen perfiden Plan: Red Death will sich mithilfe einer speziellen Konstruktion durch Flash mit Energie versorgen lassen. Die Rogues nehmen ihn zu diesem Zweck gefangen. Mark verfolgt derweil seine eigenen Ziele.
