From the opening of her own yarn shop, to the anticipated proposal from her boyfriend Richard, everything seems to be working out for Tabitha Grey. That is until the 'sweater curse' starts to come into play... a theory that from the moment you make something for your partner, disaster will be around the corner. After finishing her crochet cashmere sweater for Richard, she comes home to find him with another woman. Following a shattering break up, Tabitha impulsively gathers together everything she's ever made him, taking the crochet goods to the local charity shop and out of her life. But it isn't long until the fateful jumper reappears, on a mysterious man emerging from a narrowboat along the canal. Cooper seems to be everywhere in her small town, and while Tabitha tries to distance herself from everything that connected her to Richard, she can't seem to stop running into Cooper. Amidst a growing attraction to the new resident, and the possibility of a second chance with Richard, Tabitha finds herself tangled up in a series of events that threaten to throw her plans overboard.
