Homer, Moe, Lenny and Carl win $200,000 in the Springfield Lottery. But when Carl takes off to Iceland - his homeland - with all the winnings, the guys embark on a Nordic adventure to get the cash back. Then, Marge mistakes a swinging Ashley Madison-type website for a Dolly Madison-type cupcake site, not realizing it's a destination for married people seeking liaisons. On the site, she meets the charming "Ben", who pursues her after they learn they share a love for a "Downton Abbey"-type TV series.
