在这部我的爸爸是同性恋剧情片中,Hallmark家庭電影頻道播出「Jack」(片名中譯:十五少年時),這一部有關青少年的成長劇,改編自同名小說。故事發生的年代是1982年,主角傑克(Jack)是一名15歲的高中生,他和其他同齡的青少年沒什麼兩樣,平常生活煩惱的不外乎學校、球賽、還有賀爾蒙挑動的種種情竇初開的瑣事。
不過,老天總愛開玩笑,剛剛遭遇父母離婚而亂了步調的生活,偏偏又選擇在最不合時宜的時刻,轉了個天大的彎兒。話說,傑克某天和老爸划船出遊,進行每週一次親子相處的所謂「品質時間」,當他們划行到杳無人煙的野溪河心時,他那離婚的老爸居然向他出櫃:「你知道,我的朋友包柏…,ㄛ,包柏和我是一對愛人,」話沒說完,亂了方寸的傑克,不敢相信自己聽到的事實,於是直接反應就是跳河。隨著這一跳,傑克週遭已經不怎麼平順的世界也隨之徹底翻覆河底。
Jack, in full puberty, not only has to deal with his parents' divorce, but also feels his world is falling apart when his dad tells him he is living with a man. He slowly comes to terms with his own feelings when the girl he has a crush on turn out to have a gay dad as well and his best friend's parents end up not having the perfect marriage Jack thought they had.
