Tessa is seventeen and passionate about life. Diagnosed with a terminal illness, she determines to use every moment, compiling a catalogue of what normal teenager would experience, including losing her virginity and taking drugs. With the help of her friend, she sets the list in motion.

Falling in love with Adam, her new neighbor, wasn't on the list, but it proves to be the most exhilarating experience of them all.
