Mae and George are so loved-up they haven't spent a moment apart since they met. But when George goes away to a wedding, Mae realises that she's forgotten how to be on her own. As her intense separation anxiety spirals out of control, Mae turns to her new sponsor, Maggie, for support. While her old addictive behaviours threaten to drag Mae under, George has her own problems: she hasn't told anyone that she's in a relationship with a woman, and none of her friends even know that Mae exists.
