When Alix's charismatic girlfriend, Swanee, dies from sudden cardiac arrest, Alix is overcome with despair. As she searches Swanee's room for mementos of their relationship, she finds Swanee's cell phone, pinging with dozens of unread texts. Unsure what to do, Alix reads the text messages, all of which are sent from a mysterious contact "L.T." The most recent text reads: "Please tell me what I did. Please, Swan. Te quiero. I love you." Shocked and betrayed, Alix comes to learn that Swanee's been leading a double life dating a girl named Liana for the entire time she's been with Alix. Alix texts Liana from Swanee's phone, pretending to be Swanee in order to gather information, before finally meeting face-to-face to break the news. Brought together by Swanee's lies, Alix and Liana lean on one another to come to terms with her death. Soon, their connection deepens, and the two find themselves falling in love. But Alix is still hiding the truth from Liana - she was the one sending the texts from Swanee's phone, pretending that Swanee was alive. Alix knows what it feels like to be lied to but will coming clean to Liana mean losing her, too?
