Tennis player turned coach Tashi has taken her husband, Art, and transformed him into a world-famous Grand Slam champion. To jolt him out of his recent losing streak, she signs him up for a "Challenger" event — close to the lowest level of pro tournament — where he finds himself standing across the net from his former best friend and Tashi's former boyfriend.
Treasure hunter Ben "Finn" Finnegan has sunk his marriage to Tess and his trusty boat in his obsessive quest to find the legendary Queen's Dowry. When he finds a vital clue that may finally pinpoint the treasure's whereabouts, he drags Tess and her boss, billionaire Nigel Honeycutt, along on the hunt. But Finn is not the only one interested in the gold; his former mentor-turned-enemy Moe Fitch, hired by rapper-turned-gangster Bigg Bunny, will stop at nothing to beat him to it.
