One year after the events of the second film, Petra Parker plans to propose to Marius John Watson, who has just made his Broadway musical debut. Later a meteorite lands at Central Park, and an extraterrestrial symbiote follows Petra to her apartment. Harriet Osborn, seeking vengeance after her mother's death, attacks Petra with weapons based on her mother's Green Goblin technology. The battle ends with Harriet crashing out and developing amnesia, wiping out her memory of Petra as Spider-Woman. Meanwhile, police pursue escaped convict Felicity Marko, who visits her husband and dying son before fleeing again, and falling into an experimental particle accelerator that fuses her body with the surrounding sand, transforming her into the Sandwoman, with powers to control sand and to deform at will.
