Erica (Gemma Chan) is a beautiful young lesbian girl who can't pluck up the courage to tell her traditional Chinese family who she really is. When she meets confrontational, enigmatic Kate (Katie Mcgrath), Gemma realises that she can't continue hiding herself away.

Coming out to her brother hasn't gone well for Erica (Gemma Chan). He has reacted by setting her up on an internet date with garrulous, unmarriable Scotsman Callum (Greg McHugh). The date starts badly and quickly becomes disastrous, but somehow a weird kinship emerges.
