This is basically a miniseries about Elektra fighting the Snakeroot Clan of The Hand.
Daredevil is barely in it, but he cameos to stop Elektra from killing Hand members.
There are some additions to Elektra’s history worth noting.
Tekagi, the leader of the Snakeroot Clan, had a brief affair with Elektra in the past.
By the end of this series, she kills him.
Also, Elektra consults with Nick Fury about possible members of her own clan, which she’s trying to get started. I think this is the first indication that Elektra wants to lead an organization, rather than be a lone ronin for hire.
