Maya Sulliway (Rachael Leigh Cook) is a struggling single mom who’s studying to become an accountant. When her young daughter goes off to sleepaway camp, Maya accepts a summer internship at Kizzmit, a tech company known for developing a popular social app, in order to receive college credit. There, the thirtysomething Maya feels out of place among the company’s hip millennial interns and feels even more intimidated when she meets Colin Fitzgerald (Lucas Bryant), Kizzmit’s strait-laced CFO, who has a reputation for being a highly demanding boss.
When she’s introduced to Will Martin (Travis Milne), the company’s handsome and charismatic CEO, Maya learns about Pitch-Fest, an upcoming contest designed to determine who among Kizzmit’s staff can come up with the best idea for a new app. Before long, Will and Colin both take a liking to Maya and a competition heats up between them. As she starts becoming attracted to each of them — and agrees to a date with Will — Maya overhears a conversation revealing that Kizzmit is having financial problems and the company’s investors are threatening to cut financing unless a lucrative new app is created.
Combining her passion for outdoor activities and charity, Maya comes up with an idea for an app that would allow its users to donate to charitable organizations while they exercise. Though he knows Kizzmit would greatly benefit from her app, Colin, having fallen for Maya, tells her to keep the idea for herself and not give it away at Pitch-Fest. He also expresses concern that Will, a known womanizer, is going to end up breaking Maya’s heart. Later, when Will unscrupulously steals Maya’s app idea — falsely accusing Colin of being the thief — and publicly declares it Kizzmit’s latest creation, Maya is devastated. Furious at Will and Colin, she quits her internship and storms off. But when she discovers that Will stole her idea and that Colin was not involved, the industrious accounting student wonders if there’s a way she can complete her internship and reclaim the app she invented. Along the way, she just might find a summer love.
