Jane Villanueva, 23, is determined not to be like her mother, who had her at 16. She’s studying to become a teacher while working at a hot Miami hotel, and engaged to a patient detective named Michael. Her one guilty pleasure? Watching telenovelas with her young-at-heart mother, Xiomara, and her devout grandmother Alba. And like a scene straight out of a telenovela, Jane, at a routine check-up, is accidentally inseminated with a specimen meant for the woman in the next room. Amazingly, the specimen is Rafael’s, her former crush and current boss. Weeks later, the unsuspecting (and expecting) Jane is faced with the most complicated decisions of her life.
In the middle of the night, Jane gets a burst of creative energy and starts her thesis. Unfortunately, Mateo spills orange juice all over her computer causing it to crash and Jane loses all her hard work.

Jane and Rafael begin estate planning for Mateo, but when Jane realizes that Mateo will inherit millions, she worries he will become spoiled.
Jane thinks she is finally ready to make a decision about her love life. Alba has taken the proper steps to become a citizen, but Xo’s past might make it more difficult than anyone was expecting.
As Jane tries to juggle motherhood and school, she forgets to plan Lina’s surprise 25th birthday party leading to friction between the best friends.
When a slot opens up in the graduate program that Jane has been waiting for, she is faced with her first big motherhood dilemma – leaving Mateo sooner than expected.
Jane is finally in a rhythm with Mateo, but finds herself out of step with Rafael and Michael and the potential love triangle that is brewing between them.
After Jane discovers Mateo’s abduction, chaos ensues, especially when they all learn Sin Rostro is involved and demanding a ransom.
