On the first day of school, Javier is confused. In looking for the boys washroom, he mistakenly enters the girls washroom. There he sees Angeles and immediately falls in love. His new love, however, is not as sweet and enchanting as she seems.

A little girl catches a cold from her seatmate at school, chickenpox from her little brother, and other illnesses from other people, but there is one contagion she really does want to catch.
