Submarine

Fifteen-year-old Oliver Tate has two big ambitions: to save his parents' marriage via carefully plotted intervention and to lose his virginity before his next birthday. Worried that his mom is having an affair with New Age weirdo Graham, Oliver monitors his parents' sex life by charting the dimmer switch in their bedroom. He also forges suggestive love letters from his mom to dad. Meanwhile, Oliver attempts to woo his classmate, Jordana, a self-professed pyromaniac who supervises his journal writing - especially the bits about her. When necessary, she orders him to cross things out.
