Motorcycle Summer (1975)

On his 18th birthday, Māris receives a motorcycle from his parents, and, while driving around with his friends, they pass a wedding car. The bride, Inese, is entering a loveless marriage, so she allows Māris to "steal" her from the wedding reception. They take a romantic ride and end up spending the night at a remote house in the countryside. They spend the following night in the forest by a campfire, but in the morning Inese is missing. Māris swears to find her and prove his newfound love.
