Madame Web

In 1973, a research team led by Ezekiel Sims and his pregnant partner Constance Webb discovered an unidentified species of spider in the jungles of Peru with rare healing properties. Ezekiel betrayed the team and claimed the spider for himself before leaving Constance for dead. An indigenous tribe attempts to save Constance, but she dies shortly after giving birth to a girl whom she names Cassandra.
