It's March 2020 and the UK is on the verge of locking down due to Coronavirus. On a night out, Miles runs into Alex and they end up back at his place to sort out their differences. A bout of food poisoning renders Alex helpless and unable to leave the house. The country is plunged into lockdown and Alex and Miles are stuck together. With so much resentment between them after their break-up in 2018, they vow to be nothing but housemates while they both write the new albums they need to deliver. As time goes on and the lockdown never seems to end, will they be able to keep out of each other's way, or will their feelings get the better of them, and will they ever get to the bottom of what drove them apart in the first place?
