In the novel, Regalado depicted the City of Manila during the American occupation of the Philippines[1] but before World War II.

[3] Set during the second decade of American occupation and colonization of the Philippines, Regalado invented in Sampagitang Walang Bango the characters Bandino, Nenita, Pakito, and Liling.

Apart from being a narrative about infidelity, particularly in the so-called wealthy and high-class people of Manila, the 271-page novel described a Philippine society when its traditional Filipino values were being tarnished and windswept by the norms and lifestyles from the Western world.

Sampagitang Walang Bango was written by Regalado during a time when the "highly westernized middle and upper classes" of Filipinos were beginning to appear and establish themselves in Philippine society.

[4] The mixed themes of "love, self-control, and infidelity" were portrayed by the author as events that happened within a "carnival-like milieu".
