At twenty-nine, police officer Erica Salinas is determined to eliminate as many gangs as she can from the streets of Chicago. When she's offered an opportunity to go undercover as a student at an inner city high school to stop the drugs trafficking its halls, she jumps at the chance. It doesn't take long for her to identify the two gangs ruling the school and get offered drugs, but she isn't satisfied with runners. She wants the dealer and supplier. She befriends a boy who has connections with one of the gangs, hoping to get closer to her goal. Instead, she finds herself getting attached to the kid and falling in love with his older brother, Derrick. Erica knows she is putting the case at risk by getting too involved. And when she spots a gang allegiance tattoo on Derrick's wrist, she'll have to decide if her career and avenging her sisters death is more important than love.
