When Greg and Jen hire Allie, a private chef, to cook for them on Valentine's Day, the evening isn't as romantic as they had hoped. Also, Matt and Colleen try to adopt a dog from Ruth, a judgmental animal advocate; John and Joan attempt to buy a classic car from dealership owner Gavin; and Sophia gets a necklace from a boy for Valentine's Day, to the chagrin of Heather and Tim.

Dinner gets awkward for Jen and Matt when they find themselves alone without Greg and Colleen; Heather and Tim try to sneak wine into an ice skating show to get out of paying at the venue; Lark accidentally locks out Greg and Jen from the house, prompting Greg to install a complicated home automation system; and John and Joan agree to an impromptu wedding after Colleen mentions that she's an ordained minister.
