Poppy and the twins attempt to convince a reluctant Douglas to wear a silly costume; after he finally puts it on, he meets the woman of his dreams, who he now is sure will not take him seriously. Meanwhile, Angie struggles to tell her boss that she needs to leave work to be with her son on Halloween, leaving Graham's costume in limbo.

Will encourages Angie to rediscover her passion for heavy metal music by taking a guitar class, and in turn, Angie insists that Will get back in the field covering weather by driving both of them into a storm. Meanwhile, the rest of the gang explore their romantic passions as Douglas pursues his crush on Big Red with the help of Miggy, and Poppy feels an instant connection with a dreamy musician.

Douglas agrees to babysit the kids on Valentine's Day, but when Graham finds himself in a Valentine's Day emergency and Big Red shows up unannounced, Douglas and Big Red band together to help Graham. Meanwhile, Will and Miggy celebrate "Palentine's Day" together - a day honoring the love of two friends - but when they run into Angie at her second job, they help her finish her deliveries so she can be with Owen on Valentine's Day.

It's Valentine’s Day! Will and Angie have reunited to help run the student-parent dinner at Hilltop, where the kids are serving up questionable meals to paying customers. Meanwhile, Big Red is back in town and Douglas is worried about how Poppy will react.
