The plot revolves around Phua Chu Kang (Gurmit Singth) being persuaded by his mother Ah Ma (Neo Swee Lin) to bid for a contract to renovate the Heaven Can Wait old folk's home owned by the unscrupulous Lim Lau Pek (Henry Thia). Although he is not sure why Ah Ma wants so badly for him to get the job, he agrees to do it anyway when he finds out that his arch-rival Frankie Foo (Lim Kay Siu) is also bidding for the same contract.
My Dearest Señorita, produced by Javier Calvo and Javier Ambrossi, is an adaptation of the 1972 Oscar-nominated film of the same name directed by Jaime de Arimañán, who co-wrote the script with José Luis Borau starring José Luis López Vázquez.
