Dayo combines paperless 2-D and 3-D technologies in presenting a fantasy film ripe with figures from Pinoy mythology. It tells the story of an 11-year-old kid named Bubuy (voiced by Star Circle Grand Kid Questor Nash Aguas) out to save his grandparents, who have been abducted into Elementalia, a fantasy land with strange flora and fauna.

At Elementalia, Bubuy meets Anna Manananggirl (voiced by Katrina Legaspi), a hyperactive teener with a special affection for all things human–but not of the tummy-filling kind. Their adventure takes them from massive falls teeming with gravity-defying merfolk to crystal caves housing swarms of alitubi; and from a grand old tree, home to a motherly kapre, to a majestic mountain guarded by a pack of hungry aswang.

Directed by Robert Quilao, Dayo also features the voice talents of Laurice Guillen, Peque Gallaga, Nova Villa, Noel Trinidad, Pokwang, and Michael V. Gerard Salonga does the film score, with Lea Salonga performing the theme.
