There's a new student in Norrisville high school. "The name's Samantha by the way, but you can call me Sam." she said to the two boys, Randy Cunningham, and Howard Weinerman. They all ended up as best friends, but every time a shadow monster comes out, Sam's gone. Well that's because she is the BLUE ninja. Later on, Randy and Sam starts to hang out more than every day at school. Is this a sign, or a trap? Sam doesn't want to fall in love, because she doesn't want Randy to get hurt, but what she don't know is that Randy is also a NINJA as well, but red. Will they show out there love, or just be friends?
