Arvee, a distinguished and intellectual mouse, hates having to leave his laboratory home and become a family pet. To his surprise, though, life in Paradise Villa, his exquisite new house, is delightful - but it is dull. Then Arvee meets Stringer and his family of brown mice, and learns an awful truth. Paradise Villa has been taken over by Pasha the devilish Ratlord and his hench-rats. They will stop at nothing to enslave every mouse in the house. Using all his genius and courage, Arvee sets out to liberate the mousy masses once and for all!
