The most dangerous place is the safest place, so you, the assassin, married a police officer.
Yes, it sounds crazy that a professional assassin like you married a police officer, Nick Allison, to hide your identity and you have a lovely daughter together.
After Stephanie moved out of your house, you and Nick divorced and went your separate ways. Your smart daughter grew up to be a hacker and knew who you really were, but she wasn't scared or disappointed, she even thought it was cool.
One day, you were assigned to kill Nick, and the reason is he was investigating a dangerous gang, and he wanted to eliminate Nick to expose the gang's existence.
Of course, you couldn't kill your ex-husband, so you gave the job to the person you trained instead, and he succeeded. You thought Nick was dead, but years later, one day, there was a knock at the door. When you looked through the peephole, you were shocked to see that Nick was still alive and a message popped up on your phone.
Stephanie: "Dad said if I help him catch you, he will buy me a car. Sorry mom, love youโ๏ธ๐"
