Eight years after a one-night stand, Sophie Archer raises son Jack alone until he's diagnosed with leukemia requiring a rare blood-type donor. Doctors suggest a million-dollar imported medicine to buy time. While struggling financially, Sophie becomes Caleb Johnson's secretary, unaware he's Jack's father. Meanwhile, Caleb and his grandmother Kate meet Jack by chance and confirm paternity through DNA testing. As Sophie and Caleb develop feelings and she becomes pregnant again after another encounter, Sophie saves enough for Jack's treatment, only for rival Chloe Bradford to destroy the medicine. Kate intervenes, recognizes Sophie and Jack as family, and tells Caleb to marry Jack's mother, not realizing he's already falling for Sophie. When Caleb discovers Sophie is Jack's mother, they commit to each other. At their wedding, Sophie reveals she has no blood relation to the Archers, and learns she's actually the biological daughter of the Bradfords couple, whom she refuses to forgive. The story ends with Sophie giving birth to twins and living happily with Caleb, Jack, Kate and their growing family.
