Elektra (2005)

Shrouded in mystery. Tainted by tragedy. Trained to kill. Then left for dead. But for Elektra, death was just the beginning. Now she is back... with a vengeance. Although her sensei has trained her well in the strict discipline of ninjutsu, he cannot begin to tame her burning rage over the brutal murder of her parents. She becomes an assassin - the best in the business. But for a woman like Elektra killing is no way to make a living. To save herself, Elektra needs something more than a reason to kill... she needs a reason to live.
