Earlier today (September 3), Jordy Lucas - who plays Summer - announced that she will be leaving the soap in the coming weeks. Her final scenes will air in early 2013.
Show chiefs have now confirmed that life will be far from quiet for Summer before she makes her exit.
An official statement on Channel 5's Neighbours website explained: "The drama isn't over just yet - Jordy's exit storyline is set to raise a few eyebrows, with Summer finding herself embroiled in a romance that will test her moral compass."
More details on the final storyline are expected to be disclosed later in the year.
Neighbours airs weekdays at 1.45pm and 5.30pm on Channel 5 in the UK, and weekdays at 6.30pm on Eleven in Australia.
