With his debut solo album on the horizon, 22-year old Something Corporate singer Andrew McMahon expected big things in 2005. Leukemia wasn't one of them. DEAR JACK chronicles McMahon on a rollercoaster year, through the highs of recording and releasing a solo album (under the name JACK’S MANNEQUIN) and the lows of being diagnosed with leukemia and breaking up with the love of his life. The film opens on the day Andrew is diagnosed and follows him through every scary, life-changing and intensely personal event that follows. It also flashes back to this childhood, the making of the JACK’S MANNEQUIN album and his collaboration with Tommy Lee, one of the last concerts he played before becoming ill, and his relationships with the two most crucial women in his life, his sister and her best friends. DEAR JACK is a breathtakingly emotional film, as well as a testament to family, friends and, perhaps more than anyone will ever know, a love of making music.
