...Day is the beginning of everything in life... Day is the first creation of God but Women is the last thing He created...

Walang Katapusang Tag-araw focuses on two strong-willed women, Matilde and Binyang, who clawed themselves up, in almost simultaneous and parallel ascent to the good life. Set in Sampaloc, Manila in the 60s, the women's lives intertwine in their rivalry over Amando, scion of rags-to-riches neighbor gigolo, Leo.
