Hujan lebat menyebabkan Upin & Ipin kebosanan berdiam di rumah sahaja, tetapi mereka dididk oleh Opah bahawa hujan itu rahmat dari Tuhan. Senyap-senyap, Upin & Ipin merancang sesuatu yang memerlukan imaginasi, iaitu membayangkan diri mereka merupakan dua pahlawan yang hendak menyelamatkan Puteri Mei Mei dari genggaman Jarjit si lanun.
