Simran and Radhika, two best friends, have just passed out from their summer training for being part of a team of four hundred agents of a program called the Locker Security Squad (LSS) created by the Intelligence Bureau (IB) of India. Their job is to attend a school located near the border and help maintain security of the premises, for that school, along with many others, contains a vault with the nation's secrets that are not to be disclosed to anyone at any cost. As they start their duty, they face many problems, like their new partners and judgmental team, incidents and close encounters with a team of professional robbers, and a new corrupt head, causing a nuisance. Will they succeed in the problems they face?
