Entre vías 1995 on netflix

Lola, Kike and Santi are three bored friends stuck in some archetypal Spanish backwater with nothing to do but form dodgy rock bands, play in fairgrounds, or hang around deserted railway depots. In the latter they find a gun, which Lola takes care of, not trusting the macho posturing of her friends. Both are in love with her, and she seems to respond warmly to each. In a cafe, as they await her decision, she responds angrily to a drunk.
