West Berlin in the mid-1980s. Felix goes on a day trip to the east of the city and has a chance encounter with Thomas. The pair quickly fall in love, but their relationship is hampered by the wall which divides their city. Felix visits regularly but must return every night before curfew, and his visits eventually arouse the suspicion of the East German police, who call Thomas in for questioning. It soon becomes clear that there is only one answer to their problem: they must find a way for Thomas to escape.
