One by One

What happen's when two people who have never meet each-other in their lives, are forced to work with each other, to assassinate the one boy band that the whole population of teenage girls are obsessed with?
Riley and Ashton must work under the order's of their boss, Drake.
Drake's orders are to seduce One Direction and assassinate them, silently.
As painful it is to Riley to kill One Direction, Riley is tempted to keep Liam to herself and tell Drake that she's killed him. While on the other hand Ashton is thinking of ways of how to kill them, Which knife out of her collection...Yes she has a collection of knives...to kill them with and practicing what she's gonna say to them when she kills them.
Drake assigns Riley and Ashton one British boy band, super star at a time, and within a certain amount of time they have to be dead, or Drake assassinates them himself.
The prize to killing the boy Band, is big enough to not work for the rest of your life.
Ashton sees this...case... as the dream job of her life, ever since she found out One Direction existed, she's wanted to dice them up into pieces.
Where as Riley likes listening to their music, but isn't a 1D fan, or a Directioner. Riley does like Liam, just a tiny bit, well maybe a bit more than like... So i guess shes a Liamdarian.
But how does these two strangers get along, fighting beside each other, on a mission to kill One Direction?
Will a love story unravel between One Direction, Riley and Ashton?
All that Riley and Ashton know is that they need to pick them off One by One.
