Hold Back the Night.

A young woman joins a group of protesters trying to stop the construction of a highway through a forest with the purpose of having sex with their leader. But when morning comes and the authorities show up to disband the protesters, she hits a man with a log. This causes the two to have to go on the run. With the help of a sickly, but sympathetic woman, the two slip through police roadblocks. Traveling with her, they learn she is an ex-army lesbian who just wants to see a final sunrise at the Orkney Islands before her death.
