Young Jimmy Spencer has been missing Sunday School of late, this situation not sitting well with the new volunteer Sunday School teacher, Rachel Lynde. She learns that he has been missing because he has been working for Alexander Abraham, known to be one of the meanest men in Avonlea. Alexander is also known not to like women in particular. When Rachel goes to Alexander's house to look for Jimmy, she learns that Jimmy is not there, but is in hospital with smallpox. As such, the house is under quarantine for two weeks, which means that Rachel, along with Alexander, are also under quarantine. But before they learn this information, Sara and Felix sneak into the house and thus are also now under quarantine. If the smallpox does not get the four, they may kill each other before the two weeks are up.
