Riley North is the main character in the movie "Peppermint," played by Jennifer Garner. She is a devoted wife and mother who witnesses the brutal murder of her husband and daughter in a drive-by shooting carried out by members of a drug cartel.
After the justice system fails to provide her with the justice she seeks, she disappears for five years and trains herself to become a lethal vigilante. When she returns to Los Angeles, she embarks on a mission of revenge against the people responsible for her family's death, targeting the drug cartel's members one by one.
Throughout the movie, Riley is shown to be a highly skilled fighter, with a proficiency in firearms, hand-to-hand combat, and strategic planning. She is motivated solely by her desire to avenge her family's deaths and bring the perpetrators to justice, and is willing to do whatever it takes to achieve her goal.
Despite her violent tendencies, Riley is depicted as a sympathetic character, with the audience rooting for her to succeed in her mission. The character is also shown to have a strong moral code, as she targets only those responsible for her family's deaths, and seeks to protect innocent people caught in the crossfire.
