Baby, an aspiring architect, works with her family of con artists to earn a living and provide for her mother's medical needs. Complications arise with some failures in their recent operations, one of which is in the home of the Lamadrids.

Baby leaves home to pursue her studies, but her plans are thwarted when she chances upon the Lamadrids once again. Compelled to seek her adoptive father Badong's help, Baby receives a revelation that surprises both her and Diana.

Urgently needing funds for Osang’s worsening condition, Baby takes on one last job to pretend as Diana’s long-lost sister Amy and steal from the wealthy Lamadrids. However, an eagle-eyed Julius decides to make sure that Baby is truly his wife’s kin.

Baby successfully steals the diamonds from the Lamadrids, but her much-awaited freedom gets thwarted once again when she bumps into Julius’ first wife, Jacinda Sebastian. Much to Baby’s trouble, her and Diana’s DNA test result arrives unexpectedly.

Badong flies into a rage upon learning that Baby returned the diamonds in light of her and Diana’s DNA test results. While the Abiogs’ financial situation turns desperate, Baby’s web of lies gets more tangled as she meets more people in Diana’s life.
