Obviously (is it?), the second movie is a sequel of the first one.

Before Sunrise is about a young couple who met in a train fell into each other and sped the whole night talking to each other in Vienna. The funny thing is (even though it's not a funny movie) that they just part each other in the following morning and they are never able to see each other again.

Before Sunset is about that couple finally meet again in Paris after about 10 years, and again spend a whole day talking to each other.

Interesting thing about these movies is that other than the two main characters, no one else seem to have any significant lines. The two people keeps talking constantly from the beginning to the end. You may feel bored already, but it is really not boring, and actually you will end up getting amazed about how such a movie could keep the audience so focused and entertained (not bored at least).

Before Sunrise has 100% in rotten tomato user ratings, and Before Sunset has 94%. User ratings in imdb are also very good: 7.8 and 8.1 respectively.

I can guarantee that you will also like these movies.
