King Lear Summary Help.?

Hi, I go to a public school and i have to do a king lear summary which lasts for 15-20 mins meaning my handout must be at least 3 pages long, however i HAVE NO idea what to talk about on the topic of Religion in King Lear other than the fact that the characters are praying to the gods for comfort in the midst of all the injustices , but in return are all met with negative responses and how shakespeare is skeptical about God and the whole idea of divine justice
