Children's animation in which a newly arrived angel in Heaven skips school for angels and sets about defining for himself the behaviour befitting of a 'little angel'. When the five year old Littlest Angel (voice of Caleb Wolfe) arrives in Heaven to meet God (Ron Perlman) he is immediately enrolled at the Angel's Academy. The Academy is where budding angels learn about performing good deeds and grow their wings. The Littlest Angel, however, much prefers chasing butterflies, climbing trees and engaging in other childish delights. None of it is the same, though, without his 'treasure box', left behind on Earth. The Littlest Angel resolves to go an adventure with Halo (Ed Kelly), his talking dog, to reclaim his most prized possession.
