Anand is always busy building gadgets and machines out of odds and ends around the house, sure that each one will be a great invention. One of his projects is a burglar alarm meant to keep the family safe. As usual, his clever plans do not work out quite as expected, and his inventions lead to funny, messy results rather than success. Through Anita's amused eyes, we enjoy Anand's energy, imagination and determination. The story celebrates a young mind that keeps trying and creating, and shows the warm, teasing bond between a brother and a sister.
