After getting unexpectedly dumped by her boyfriend, Chelsea (Emily Osment) a high-brow, Harvard-educated intellectual and aspiring novelist is forced to move in with her bubbly, carefree, not-so-intellectual West Coast sister, Claire (Olivia Macklin), and her three lovably eccentric, not-so-intellectual roommates: Grant (Gregg Sulkin), a distractingly handsome personal trainer, Solana (Cinthya Carmon), a former lawyer turned healer, and Jayden (Michael Hsu Rosen), a social media influencer. But Chelsea's tough, sometimes judgemental exterior starts to soften as she gets to know her new friends, and they begin to form an unlikely found family.
