The Lock-In Liability

It was supposed to be a night of team building and pizza, but for Penny Lane, the Senior Lock-In is a covert operation to keep her infant brother hidden from the administration to save her valedictorian status. When the school's notorious player, Archer West, discovers her secret in the library supply closet, they strike a deal: he helps her babysit, and she helps him pass Calculus. But as the night wears on and a rumor spreads that they are the baby's parents, the line between fake and real begins to blur.
