Tenley Sweeney is a San Francisco based horticulturalist with a focus on sustainability. Afraid to put herself out romantically, she has long had a crush on Jared Carr since they met on an online sustainability forum a year ago - his focus on reducing plastics - they never yet having met in person. Urged by her best friend and roommate Cami to take a chance, Tenley does ask Jared out for an in-person date, he agreeing to meet for coffee. When he ends up standing her up, she learns the reason is that he was involved in a bicycle accident en route to their meeting, he in the hospital unconscious with a concussion. In the rush to be by his side, Tenley, at the hospital, is unaware until after the fact not only that the hospital mistook her for Jared's wife, but that she signed the consent form for them to continue treatment, which ended up saving his life. In this confusion, she is also mistaken as his wife by his family: his parents Lynn and Ronnie, his two teenage sisters Betsey and Faye, and his best friend and business partner Everett. The harder she tries to tell them the truth, the more reasons arise that prevent her from doing so. While the Carrs as a collective welcome Tenley into their family, Everett is suspicious of this new woman in their lives, namely why Jared never would have mentioned her let alone that they are married. The latest obstacle in telling them the truth is they needing her sustainability expertise in Jared's place to save his and Everett's start-up business - Jared who handles the sustainability side, Everett the financial side - and which Lynn and Ronnie have mortgaged their house to help. Beyond continuing the ruse, the problem for Tenley in spending concentrated time with Everett becomes their increasing mutual attraction.
